explain_fprintf_or_die(3)				     Library Functions Manual					 explain_fprintf_or_die(3)

NAME
       explain_fprintf_or_die - formatted output conversion and report errors

SYNOPSIS
       #include <libexplain/fprintf.h>
       int explain_fprintf_or_die(FILE *fp, const char *format, ...);
       int explain_fprintf_on_error(FILE *fp, const char *format, ...);

DESCRIPTION
       The  explain_fprintf_or_die  function  is  used	to  call  the fprintf(3) system call. On failure an explanation will be printed to stderr,
       obtained from the explain_fprintf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_fprintf_on_error function is used to call the fprintf(3) system call. On failure an explanation  will  be  printed  to  stderr,
       obtained from the explain_fprintf(3) function, but still returns to the caller.

       fp      The fp, exactly as to be passed to the fprintf(3) system call.

       format  The format, exactly as to be passed to the fprintf(3) system call.

RETURN VALUE
       The  explain_fprintf_or_die  function  only  returns on success, see fprintf(3) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_fprintf_on_error function always returns the value return by the wrapped fprintf(3) system call.

EXAMPLE
       The explain_fprintf_or_die function is intended to be used in a fashion similar to the following example:
	      int result = explain_fprintf_or_die(fp, format, ...);

SEE ALSO
