  You could write a wrapper for printf, "myprintf",
  that will call printf and then do minimal error handling.

#include <stdio.h>
#include <stdarg.h>

int myprintf( char const * format, ... ) 
{ va_list args;
  va_start( args, format );
  int const result = vprintf( format, args );
  va_end( args );
    
  if( result < 0 )fprintf
  ( stderr, "Error: printf failed with return code %d\n", result );
    
  return result; }
