GETSOCKNAME(2)						      BSD System Calls Manual						    GETSOCKNAME(2)

NAME
     getsockname -- get socket name

SYNOPSIS
     #include <sys/socket.h>

     int
     getsockname(int s, struct sockaddr *name, int *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.
