Unfortunatel, since you did not format your code block properly (i.e. between <pre> tags) there are some bits missing, so I cannot compile what you have here. Please edit your message add the tags, and format the code, so it shows like :
I did not realize that, when I copied the code onto this forum. everything disappeared when the signs < > appeared. Thus, #include <iostream> appeared only as #include, and <T> or <int> never appeared. I'm trying to find out how to edit the posting.
P.S. Apparently this problem occurred because I had not checked the "Treat my content as plain text not as HTML" button. I have now corrected this situation. The listed program is now complete as it appears in the book.
I don't disagree with your chiding but you answered a different question in that message. He was looking for info on how to get the DLL version info here. The question/answer you refer to in the other thread was how to get the DLL file location...
... both worthy questions but, yeah, should have been asked in a different forum.
Here is the MSDN information for Threadpool of I/O Completion Objects. http://msdn.microsoft.com/en-us/library/windows/desktop/ms682464(v=vs.85).aspx
But I can not use them to create my threadpool and do asyn read and write operation.Is anyone have experience of using these functions?
CancelThreadpoolIo CloseThreadpoolIo StartThreadpoolIo Thread Pools WaitForThreadpoolIoCallbacks
Would you give me a code example for these use?
Presumably you want someone to give you the code rather than just wanting to know if anyone could figure it out.
I won't be providing the code.
Presuming that no one else will either then you would need to do the following.
1. Learn basic programming
2. Learn basic IO (presumably you want to do this to files.)
3. Learn what image formats exists, and find the specifications for each. This includes 24 bit and 8 bit.
4. Write code to read a 24 bit image - using 1/3
5. Write code to write a 8 bit image - using 1/3
6. Put 2, 4 and 5 together into a program.
