NAME

explain_putchar_or_die - output of characters and report errors

SYNOPSIS

#include <libexplain/putchar.h>

void explain_putchar_or_die(int c);

DESCRIPTION

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

This function is intended to be used in a fashion similar to the following example:

explain_putchar_or_die(c);
The c, exactly as to be passed to the putchar(3) system call.
This function only returns on success. On failure, prints an explanation and exits.
