[most of code snipped]

Sorry, but your example is still not complete. What type is file?
How did you initialize file?

Maybe, you can post some complete source code, that compiles to an 
executable, and that shows the behaviour you reported.

Also, later in your example, there is

    msgbox(MW_INFO, MB_OK, "%d",fprintf(id3_file, [...]

This seems to call the windows API function MessageBox (MB_OK and
MW_INFO are defined in some windows headers), that is 
not available in stock DJGPP. Are you sure, you compiled with gcc 
from djgpp?
