explain_asprintf_or_die(3) Library Functions Manual explain_asprintf_or_die(3) 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 call- ing exit(EXIT_FAILURE). The explain_asprintf_on_error function is used to call the asprintf(3) sys- tem 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 as- printf(3) for more information. On failure, prints an explanation and ex- its, 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(); SEE ALSO asprintf(3) print to allocated string explain_asprintf(3) explain asprintf(3) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2013 Peter Miller explain_asprintf_or_die(3)
