NAME

explain_puts_or_die - write a string and a newline to stdout and report errors  

SYNOPSIS

#include <libexplain/puts.h>

void explain_puts_or_die(const char *s);
int explain_puts_on_error(const char *s);  

DESCRIPTION

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

The explain_puts_on_error function is used to call the puts(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_puts(3) function, but still returns to the caller.

s
The s, exactly as to be passed to the puts(3) system call.
 

RETURN VALUE

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

The explain_puts_on_error function always returns the value return by the wrapped puts(3) system call.  

EXAMPLE

The explain_puts_or_die function is intended to be used in a fashion similar to the following example:
explain_puts_or_die(s);
