int
     getsockname(int s, struct sockaddr *name, socklen_t *namelen);

DESCRIPTION

     Getsockname() returns the current name for the specified socket.  The
     namelen parameter should be initialized to indicate the amount of space
     pointed to by name.  On return it contains the actual size of the name
     returned (in bytes).

DIAGNOSTICS

     A 0 is returned if the call succeeds, -1 if it fails.

ERRORS

     The call succeeds unless:

     [EBADF]            The argument s is not a valid descriptor.

     [ENOTSOCK]         The argument s is a file, not a socket.

     [ENOBUFS]          Insufficient resources were available in the system to
                        perform the operation.

     [EFAULT]           The name parameter points to memory not in a valid
                        part of the process address space.

SEE ALSO

     bind(2), socket(2)

BUGS

     Names bound to sockets in the UNIX domain are inaccessible; getsockname
     returns a zero length name.

HISTORY

     The getsockname() function call appeared in 4.2BSD.
