NAME¶
explain_asprintf_or_die - print to allocated string and report errors
SYNOPSIS¶
#include <libexplain/asprintf.h>
int explain_asprintf_or_die(, ...);
int explain_asprintf_on_error(, ...);
DESCRIPTION¶
The explain_asprintf_or_die function is used to call the asprintf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_asprintf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_asprintf_on_error function is used to call the asprintf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_asprintf(3) function, but still returns to the caller.
RETURN VALUE¶
The explain_asprintf_or_die function only returns on success, see asprintf(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_asprintf_on_error function always returns the value return by the wrapped asprintf(3) system call.
EXAMPLE¶
The explain_asprintf_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_asprintf_or_die();
