[有進步] Once I've used freopen, how can I get the original stdout (or stdin) back?

Hello, World2
And the "Hello, World" is write into *fp points to, "foo.txt".
Mistake example

Because the "Hello, World" was be redirect to "foo.txt", althought it was already excused fclose(fp), but we got nothing from stdout. So the better way is to using fprintf().

NAND Flash
NAND memories
NAND flash memories cannot provide execute-in-place due to their different construction principles. These memories are accessed much like block devices such as hard disks or memory cards. The blocks are typically 512 or 2048 bytes in size. Associated with each block are a few bytes (typically 12–16 bytes) that should be used for storage of an error detection and correction block checksum.
NAND devices typically have software-based bad block management. This means that when a logical block is accessed it is mapped to a physical block, and the device has a number of blocks set aside for compensating bad blocks and for storing primary and secondary mapping tables.
The error-correcting and detecting checksum will typically correct an error where one bit in the block is incorrect. When this happens, the block is marked bad in a logical block allocation table, and its (still undamaged) contents are copied to a new block and the logical block allocation table is altered accordingly. If more than one bit in the memory is corrupted, the contents are partly lost, i.e. it is no longer possible to reconstruct the original contents. Some devices may even come with a pre-programmed bad block table from the manufacturer, since it is sometimes impossible to manufacture error-free NAND memories.
The first error-free physical block (block 0) is always guaranteed to be readable and free from errors. Hence, all vital pointers for partitioning and bad block management for the device must be located inside this block (typically a pointer to the bad block tables etc). If the device is used for booting a system, this block must contain the master boot record.
When executing software from NAND memories, virtual memory strategies are used: memory contents must first be paged or copied into memory-mapped RAM and executed there. A memory management unit (MMU) in the system is helpful, but this can also be accomplished with overlays.
For this reason, some systems will use a combination of NOR and NAND memories, where a smaller NOR memory is used as software ROM and a larger NAND memory is partitioned with a file system for use as a random access storage area.

NOR Flash
http://en.wikipedia.org/wiki/NOR_flash
NOR memories
The read-only mode of NOR memories is similar to reading from a common memory, provided address and data bus is mapped correctly, so NOR flash memory is much like any address-mapped memory. NOR flash memories can be used as execute-in-place memory (XIP), meaning it behaves as a ROM memory mapped to a certain address. NOR flash memories have no intrinsic bad block management, so when a flash block is worn out, either the software using it has to handle this, or the device breaks.
When unlocking, erasing or writing NOR memories, special commands are written to the first page of the mapped memory. These commands are defined as the Common Flash memory Interface (defined by Intel) and the flash circuit will provide a list of all available commands to the physical driver.
Apart from being used as a ROM, the NOR memories can, of course, also be partitioned with a file system and used as any storage device.

How do I uninstall all of Cygwin?
http://www.cygwin.com/faq/faq_2.html#SEC20
Setup has no automatic uninstall facility. The recommended method to
remove all of Cygwin is as follows:
Remove all Cygwin services. If a service is currently running, it must first be stopped with `cygrunsrv -E name', where `name' is the name of the service. Then use `cygrunsrv -R name' to uninstall the service from the registry. Repeat this for all services that you installed. Common services that might have been installed are sshd, cron, cygserver, inetd, apache, and so on.
Stop the X11 server if it is running, and terminate any Cygwin programs that might be running in the background. Remove all mount information by typing `umount -A' and then exit the command prompt and ensure that no Cygwin processes remain. Note: If you want to save your mount points for a later reinstall, first save the output of `mount -m' as described at http://cygwin.com/cygwin-ug-net/using-utils.html#mount.
Delete the Cygwin root folder and all subfolders. If you get an error that an object is in use, then ensure that you've stopped all services and closed all Cygwin programs. If you get a 'Permission Denied' error then you will need to modify the permissions and/or ownership of the files or folders that are causing the error. For example, sometimes files used by system services end up owned by the SYSTEM account and not writable by regular users. The quickest way to delete the entire tree if you run into this problem is to change the ownership of all files and folders to your account. To do this in Windows Explorer, right click on the root Cygwin folder, choose Properties, then the Security tab. Select Advanced, then go to the Owner tab and make sure your account is listed as the owner. Select the 'Replace owner on subcontainers and objects' checkbox and press Ok. After Explorer applies the changes you should be able to delete the entire tree in one operation. Note that you can also achieve this in Cygwin by typing `chown -R user /' or by using other tools such as CACLS.EXE.
Delete the Cygwin shortcuts on the Desktop and Start Menu, and anything left by setup.exe in the download directory. However, if you plan to reinstall Cygwin it's a good idea to keep your setup.exe download directory since you can reinstall the packages left in its cache without redownloading them.
If you added Cygwin to your system path, you should remove it unless you plan to reinstall Cygwin to the same location. Similarly, if you set your CYGWIN environment variable system-wide and don't plan to reinstall, you should remove it.
Finally, if you want to be thorough you can delete the registry tree `Software\Cygnus Solutions' under HKEY_LOCAL_MACHINE and/or HKEY_CURRENT_USER. However, if you followed the directions above you will have already removed all the mount information which is typically
the only thing stored in the registry.

ANSI C, lvalue
Value (computer science)
In C: L-value and r-value
Some languages use the idea of l-value and r-value. L-values are values that have addresses, meaning they are variables or dereferenced references to a certain place. R-value is either l-value or non-l-value — a term only used to distinguish from l-value. In C, the term l-value originally meant something that could be assigned (coming from left-value, indicating it was on the left side of the = operator), but since 'const' was added to the language, this now is termed a 'modifiable l-value'.
An l-value is an expression that designates (refers to) an object. A non-modifiable l-value is addressable, but not assignable. A modifiable l-value allows the designated object to be changed as well as examined. An r-value is any expression that is not an l-value, it refers to a data value that is stored at some address in memory.

NTFS sucks!
In cygwin with NTFS of WindowsXP sp2 environment, I''d input:
mv uClinux-dist /usr/local/src
take me about 30minutes, it's really sucks!!
In Linux box, the inode will help it shorter. But why? Let me study in the Ch.11 FileSystem.

patch -p0
-pnum or --strip=num
Strip the smallest prefix containing num leading slashes from each file name found in the patch file. A sequence of one or more adjacent slashes is counted as a single slash. This controls how file names found in the patch file are treated, in case you keep your files in a different directory than the person who sent out the patch. For example, supposing the file name in the patch file was
/u/howard/src/blurfl/blurfl.c
setting -p0 gives the entire file name unmodified, -p1 gives
u/howard/src/blurfl/blurfl.c
without the leading slash, -p4 gives
blurfl/blurfl.c
and not specifying -p at all just gives you blurfl.c. Whatever you end up with is looked for either in the current directory, or the directory specified by the -d option.

Ya, I did it in today, 'cuz the AJAX operation is such slowly in Opera 9.00, and some error often occured in operation. So that, I exported all of feed to bloglines.
My buddy, Howl suggests me some useful RSS reader, I've never tried it yet, 'cuz now I prefer the on-line service (a.k.a API application). Maybe next time, I'll try these good tool. :-)

Realtek 8139
One day, we've a network curriculum in FEC, Ralph told us that the Realtek 8139 ethernet chip is good than others, 'cuz it can be program and control as we hope.
Util today, I's visited the Realtek 8139 spec webpage, the last one is 75 pages, well~ well~ well~ it's more better than the D-Link 530Tx+ for me.

Burning Tools
Because I re-partition my disc and re-install my Windows box, so I was stay in Win32 environment for setting.
Some neat utilities I prefer, like the burning CD tools. Today, I found the CDBurn.exe by Google, it's made in M$, project named "Windows Server 2003 Resource Kit Tools", and found this information in "How can I write ISO files to CD?".
So that now, I using it to burn out the Ubuntu Linux 6.06 CD for installing my Linux box later. ;)
An other tool as I found, "CreateCD"

ISO Tools
Today, I bough a joy stick to play game, include "Silent Hill" and "MapleStory" or Hafe Life".
The Silent Hill 3 that I download ISO file, thus I need to mount it then install and play it. First, I try to install the "Alcohol 50%", it's a simple version with "Alcohol 120%", without the burn CD/DVD function, and it has non-registry. Both 50% and 120% are can generate ISO file.
Second, I installed the "WinISO", but it seems older than "IsoBuster", and WinISO cannot edit files which more than 2GB, but IsoBuster can satisfied.
Finally, I tried the "DAEMON tools", it seems as the same principle like Alcohol, 'cuz durning the install procedure, it prompts a warning dialog, said something like, "If u install this program, maybe ur debugger, like ICE... cannot run well.". Ya... u know, in Unix-Like OSes, we can mount ISO file as a file node, for genernal at /mnt. Maybe these tools also did like Unix-Like.
"Daemon tools" doesn't need to registry and has no prompt dialog, haha, it's good for me, 'cuz the dialog is really really bother me... even everyone except the Darmon tool TEAM. :P
Thus... I pick and choose the "Daemon Tools" for mount ISO files. Maybe after this moment, I need to programs which support burn out a ISO files and NO REGISTRY DIALOG.

16-bit data line mode {00, 01}, {10, 11}, the MSB bit is exange by "0" and "1". 32-bit is {00, 01, 10, 11}, {100, 101, 110, 111}. The default mode is .arm, thus load the instruction to memory by 3-bits.
For parting 16-bit and 32-bit mode; it's 16-bit if LSB is 1, so "Tstart +1", is plus LSB bit to 1 to tail of machine code.
Return 32-bit mode from 16-bit, we can use "mov pc, lr".

Question What are linker script files?
Answer
Linker script:
In the Embed system development, it needs to use linker position file. This file describes the relevant information of code linker position, including code section, data section, address section, and the linker shall use the code of this file to the whole system as correct position. This file is called as linker scripts file.
The following is an example of Linker script:
SECTIONS
{
. = 0x02000000;
.text : { *(.text) }
Image_RO_Limit = .;
Image_RW_Base = .;
.data : { *(.data) }
.rodata : { *(.rodata) }
Image_ZI_Base = .;
.bss : { *(.bss) }
Image_ZI_Limit = .;
__bss_start__ = .;
__bss_end__ = .;
end = .;
.debug_info 0 : { *(.debug_info) }
.debug_line 0 : { *(.debug_line) }
.debug_abbrev 0 : { *(.debug_abbrev)}
.debug_frame 0 : { *(.debug_frame) }

What's is command script (*.cs) ?

Question What is a command script file *.cs? How can I make a command script file?
Answer
While debugging software or after the target board resetted, sometimes users may need IDE automatically finish some special functions such as resetting target board, clearing off watchdog, shutting off interrupts, memory map, etc., these special functions can be completed through executing a group of commands. This group of commands saved as a text file and is called command script file.
You can execute the command script (*.cs) file to initialize your target board before debugging. But such a file is not necessary if some programs (such as bios,bootloader) execute well after power on. The cs file for Embest Debugger is just very useful to debug a target board without any code in boot rom.
For Embest IDE, when remotely connected to the target device, we can execute the command script (*.cs) file to initialize the system before debugging. We can do as following:
Project ->Settings ->DEBUG ->Action After connected, select the command script that you want to execute.
The following are the examples of command scripts :
; stop target CPU
stop
; configurations of the special register
memwrite 0xffe00000 0x01002535
memwrite 0xffe00004 0x02002121
memwrite 0xffe00024 0x06
; configuration for Mapping Address
memwrite 0xffe00020 0x01
refresh
download -v D:\Demo\armdemo\debug\led.elf 0x2000000
;end

While debugging software or after the target board resetted, sometimes users may need IDE automatically finish some special functions such as resetting target board, clearing off watchdog, shutting off interrupts, memory map, etc., these special functions can be completed through executing a group of commands. This group of commands saved as a text file and is called command script file.
You can execute the command script (*.cs) file to initialize your target board before debugging. But such a file is not necessary if some programs (such as bios,bootloader) execute well after power on. The cs file for Embest Debugger is just very useful to debug a target board without any code in boot rom.
For Embest IDE, when remotely connected to the target device, we can execute the command script (*.cs) file to initialize the system before debugging. We can do as following:
Project ->Settings ->DEBUG ->Action After connected, select the command script that you want to execute.
The following are the examples of command scripts :
; stop target CPU
stop
; configurations of the special register
memwrite 0xffe00000 0x01002535
memwrite 0xffe00004 0x02002121
memwrite 0xffe00024 0x06
; configuration for Mapping Address
memwrite 0xffe00020 0x01
refresh
download -v D:\Demo\armdemo\debug\led.elf 0x2000000
;end

Log
Today, we have the experiment on Sec.3.1-1 and Sec.3.1-2, we know the Flash address range and RAM address range.
The Embest IDE is not stable on the PC, we don't know what's going on, PCs' or Embests' problem. Clicking the "Rest(Ctrl+R)", the entry point will be offset, advisor said that, 'cuz the entry point be taked to 0x00000000, and the "Connect" will excute the initial file (*.cs), then initial some memory addressing configuration. Thus, after Reset, entry point will be offset, and different with program specified.
Be mentioned is this section, "lsr" and "lsl", a little different. :-)

SIC/XE assembler
In this semester, one of corriculum, System Software. We need to write a SIC/XE assembler, my stuff is not be done in now, it is such buggy.
Some drawback below,
1. Generating the right objcode output.
2. The SYMTAB can be replaced by HashTab
3. Snipping some variables which doesn't used.
TODO,
1. To survey the performance with algorithm(timer) with my sutff.
2. ...
Finally, thx for somebody who has been help me for code it, especially kornelius. :)

Hi 各位，
很幸運地，我收到微軟從美國寄給我的免費 Camera。我整理出這個 eMail 討論的過程，希望幫助大家也可以如此幸運。
某天專題 meeting 完後，我回家上 Google 找 USB webcam driver，然後找到一個微軟員工的網誌 (Blog) — Mikehall's Embedded WEblog。
http://blogs.msdn.com/mikehall/archive/2006/03/01/541495.aspx，去 GotDotNet 找檔案，結果有錯誤，載點消失，所以又回報給另一個人 (Julie Sanders)。
然後，我發現 Who wants a Free WebCam ? (http://blogs.msdn.com/mikehall/archive/2006/04/17/577924.aspx)，當我現在再次回首時，才知道真的是限量名額 25 位，能得到免費的 WebCam，哈哈，真是太幸運了，當下立刻 eMail 給 Nic Sagez，我真的不曉得他要送 WebCam 給我，看來我那晚有點神智不清，呵呵。
我是 4/18 8pm (臺灣時間) 那天開始發信給他。信件標題為 "Need webcam usb driver"。
【第一封 - 4/18 8:32pm】
Hi Nic,
I am a student from Taiwan, we are develop a project base the Windows
CE platform, now we are looking for the USB webcam driver, and I got
something from Mikehall's Embedded WEblog, we need your support,
please, thanks.

哈哈，我發現我的簽名檔還滿白爛的。因為我寫我喜歡程式設計，還有 UNIX，哈哈，巴結點是否要寫喜歡 Windows series 呢？
後面會把反應 GotDotNet 寄給 Julie 信件貼出，也是滿白爛的，哈哈。
總而言之，原本自己就很白爛了。:P

當晚，我正在苦著什麼是 "Device model" 呢？是要寫發展平台呢？亦或是 WebCam 呢？我還有問佑安，佑安還問他的香港朋友呢。
哈哈，免費送的網頁就有寫到，"Nic Sagez has about 25 Logitech QuickCam Pro 5000 devices sat in his office."，哈哈，再寫一次 Logitech QuickCam Pro 5000 還滿怪的。
【第二封回覆 - 4/25 1:01am】
Hi Alan,
Your camera is in the mail and should get to you this week.
I'm looking forward to seeing your contribution to the project!
哈哈，我有職業病啦，原本我真的只是向他要 USB Camera driver 而已，然後看見 mail 這個字，以為是 eMail，現在才曉得是包裹 (DHL 的呢~)。
最後一句話讓我很感動，他這麼關心我的專題，呵呵，比小貞貞還關心啦 ~~ ^_________^
【第三封 - 5/2 9:50pm】
Hi Nic,
I'm waiting for your mail, but it's no response, could you email me
the webcam driver ?
誤會開始了，真丟臉啦，哈哈。 >"<
【第三封回覆 - 5/2 10:34pm】
Hi Alan,
It looks like the webcam has been delivered to you on the 27th of April
and it was signed by "Costamp" (I'm not sure who that is).
You can download the driver from the gotdotnet workspace
(http://www.gotdotnet.com/workspaces/workspace.aspx?id=0eb87e35-13e4-4fa
3-9fde-71e9136f47de) in the "release" section.
Let me know if you have any questions,
Thanks!
哈哈，人家很好心，結果我還是沒搞懂第一段 (算是略過)，因為他真的表明說 4/27 那天就從美國寄出包裹了。
第二次感動，也是最後一段，時時關切我的進度。
【第四封 - 5/2 11:07pm】
Oh ~~ thx, Nic.
I just forgot to visit GotDotNet website, I got it now.
BTW, you're very kind for dealing my question, thank you very much.
哈哈，兩次的感動就免不了要謝謝對方囉。真的很友善地處理我的問題呢 ~~
最後，我公佈與 Julie 的白爛對話過程。標題是 "Error page feedback"。
