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);
SEE ALSO printf(3)
