&warn.experimental.func;
|
|
<para>
|
|
<function>socket_strerror</function> takes as its
|
|
<parameter>errno</parameter> parameter a socket error code as returned by
|
|
<function>socket_last_error</function> and returns the corresponding
|
|
explanatory text. This makes it a bit more pleasant to figure out why
|
|
something didn't work; for instance, instead of having to track down a
|
|
system include file to find out what '-111' means, you just pass it to
|
|
<function>socket_strerror</function>, and it tells you what happened.

The expected output from the above example (assuming the script

is not run with root privileges):
|
|
<screen>

socket_bind() failed: reason: Permission denied

</screen>
