Wait, what? Where’s your error checking? What if your printf fails?
Actually that’s one of the things I like least about C. It leaves all error
checking up to the programmer instead of having even a minimal handler for
errors not otherwise caught.

  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; }
