explain_getresuid_or_die(3) Library Functions Manual explain_getresuid_or_die(3) NAME explain_getresuid_or_die - get r/e/s user IDs and report errors SYNOPSIS #include <libexplain/getresuid.h> void explain_getresuid_or_die(uid_t *ruid, uid_t *euid, uid_t *suid); int explain_getresuid_on_error(uid_t *ruid, uid_t *euid, uid_t *suid); DESCRIPTION The explain_getresuid_or_die function is used to call the getresuid(2) sys- tem call. On failure an explanation will be printed to stderr, obtained from the explain_getresuid(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_getresuid_on_error function is used to call the getresuid(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_getresuid(3) function, but still returns to the caller. ruid The ruid, exactly as to be passed to the getresuid(2) system call. euid The euid, exactly as to be passed to the getresuid(2) system call. suid The suid, exactly as to be passed to the getresuid(2) system call. RETURN VALUE The explain_getresuid_or_die function only returns on success, see getre- suid(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_getresuid_on_error function always returns the value return by the wrapped getresuid(2) system call.
