explain_printf_or_die(3)   Library Functions Manual   explain_printf_or_die(3)

NAME
       explain_printf_or_die - formatted output	conversion and report errors

SYNOPSIS
       #include	<libexplain/printf.h>
       int explain_printf_or_die(const char *format);
       int explain_printf_on_error(const char *format);

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

       The explain_printf_on_error function is used to call the	printf(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_printf(3) function, but	still returns to the caller.

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

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

       The explain_printf_on_error function always returns the value return by
       the wrapped printf(3) system call.

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