No. If _outfile is !=NULL after fopen there is no visible problem.

In _my_ WinDOS-Box this program

#include <stdio.h>

int main()
{
   FILE *_outfile  =  fopen("test.zzz", "wb");
   fprintf( _outfile, "%1c",  (char)10&0xFF);
   fclose(_outfile);
   return 0;
}


produces a file test.zzz containing one byte with the value 10. What
happens on your system ? What is blowing you up ? How did you verify
that fprintf "doesn't work" ? Please give details.

I think you may have been bitten by something else which is not in the
code you posted.

Huh ? Which 13 in front of which control key ???
