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 fail‐ ure an explanation will be printed to stderr, obtained from the explain_asprintf(3) func‐ tion, 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();
