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
