This is not a forum for debugging other peoples' code, but ...
1. You are using HANDLE * instead of HANDLE
2. Your logic for nul termination is totally wrong:
c->buffer[nBytesRead + 1] = '\0';
should be
c->buffer[nBytesRead] = '\0';
(think about why)
3. Your logic for detecting End Of File also looks wrong - Quote from
msdn.microsoft.com: "The ReadFile code to check for the end-of-file
condition (eof) differs for synchronous and asynchronous read operations.
When a synchronous read operation reaches the end of a file, ReadFile
returns TRUE and sets *lpNumberOfBytesRead to zero".
4. I would also personally check that CreateFile isn't returning NULL (as
well as your current test for INVALID_HANDLE_VALUE) as that will also
indicate an error. I also habitually set nBytesRead=0 before calling
ReadFile although I cannot honestly tell you if that will make a
difference.
Try that little lot and see what happens. At the worst it will let you
diagnose any real error correctly.
