NAME
       explain_printf_or_die - formatted output conversion and report errors

SYNOPSIS
       #include <libexplain/printf.h>

       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.

       exits, it does not return.

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);
