>&#13;     This function returns a socket error code.
    </P

>&#13;     If a socket resource is passed to this function, the last error which
     occurred on this particular socket is returned. If the socket resource is
     omitted, the error code of the last failed socket function is returned.
     The latter is in particular helpful for functions like
     <A
HREF="function.socket-create.html"
><B
CLASS="function"
>socket_create()</B
></A
> which don't return a socket on
     failure and <A
HREF="function.socket-select.html"
><B
CLASS="function"
>socket_select()</B
></A
> which can fail for reasons
     not directly tied to a particular socket.  The error code is suitable to
     be fed to <A
HREF="function.socket-strerror.html"
><B
CLASS="function"
>socket_strerror()</B
></A
> which returns a string
     describing the given error code.
