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) system 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);
