The .I namelen parameter should be initialized to indicate the amount of space pointed to by .IR name . On return it contains the actual size of the name returned (in bytes). .SH DIAGNOSTICS A 0 is returned if the call succeeds, \-1 if it fails. .SH ERRORS The call succeeds unless: .TP 15 [EBADF] The argument \fIs\fP is not a valid descriptor. .TP 15 [ENOTSOCK] The argument \fIs\fP is a file, not a socket. .TP 15 [ENOBUFS] Insufficient resources were available in the system to perform the operation. .TP 15 [EFAULT] The .I name parameter points to memory not in a valid part of the process address space. .SH "SEE ALSO" bind(2), socket(2) .SH BUGS Names bound to sockets in the UNIX domain are inaccessible; .I getsockname returns a zero length name.
