  19 .SH DESCRIPTION
  20 .LP
  21 \fBgetsockname()\fR returns the current \fIname\fR for socket \fIs\fR. The
  22 \fInamelen\fR parameter should be initialized to indicate the amount of space
  23 pointed to by \fIname\fR. On return it contains the actual size in bytes of the
  24 name returned.
  25 .SH RETURN VALUES
  26 .LP
  27 If successful, \fBgetsockname()\fR returns  \fB0\fR; otherwise it returns
  28 \fB\(mi1\fR and sets  \fIerrno\fR to indicate the error.
