The strerrorname_np returns error number name (e.g. "EINVAL" for EINVAL) while strerrordesc_np returns string describing error number (e.g "Invalid argument" for EINVAL). Different than strerror, strerrordesc_np does not attempt to translate the return description, both functions return NULL for an invalid error number. They should be used instead of sys_errlist and sys_nerr, both are thread and async-signal safe. These functions are GNU extensions. Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com> |
