Though a Windows program, for compatibility reasons and a greater simplicity with pointers, I am using fwrite to write to files with VC 4.2, with all patches. The problem I am having is that I am getting a corrupt file when writing to it. What happens is that I read the file, do an fseek to specific offset and write to that position. This works fine in all other cases, except that I seem to be writing more than I have indicated with this line of code:
fwrite (&buffer, sizeof(char), 3, prt);
Once again, I have an fseek just before this (which is working ok) and then write the contents of the buffer. So I shouldn't have a corrupt file problem. I used fopen with r+b, so read-write binary files. That's ok.
I've tried everything possible to solve the problem, but no luck; it's still corrupt! Your suggestions will be greatly appreciated!
