    Exclamation Using Windows File I/O functions

    Hi,
    I've made a few programs in Windows using C now, but one thing bothers me:- the fact that I use the file I/O functions defined in stdio.h when I should be using the Win32 functions. Are they any good?

    I'd like to change my current string debug file output function:-

    Code:
    int DebugCh(char *debugchar)
    {
    	FILE *fdebug;
    
    	fdebug = fopen("debug.txt", "at");
    	fprintf(fdebug, "%s\n", debugchar);
    	fclose(fdebug);
    	return(TRUE);
    }
    so that it uses Windows file I/O. The only thing is, there doesn't appear to be an equivalent for fprintf. Any ideas?

    There is no equivalent to fprintf. Either you have to run 'sprintf' or 'wsprintf' and then write the string to the file.

    If you are using Win32Api, what you do is quite fine.
    ( you should make the char pointer 'const' though and
    check for errors ).

    If you are using the MFC, try CStdioFile and it's
    WriteString method.

    When in doubt, read the FAQ.
    Then ask a smart question.
