GETSOCKNAME(2)		  FreeBSD System Calls Manual		GETSOCKNAME(2)

NAME
     getsockname -- get	socket name

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/socket.h>

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

DESCRIPTION
     The getsockname() system call returns the current name for	the specified
     socket.  The namelen argument 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).

RETURN VALUES
     The getsockname() function	returns	the value 0 if successful; otherwise
     the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS
     The call succeeds unless:

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

     [ECONNRESET]	The connection has been	reset by the peer.

     [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 argument points to memory not in a valid part
			of the process address space.

SEE ALSO
     bind(2), getpeername(2), socket(2)

HISTORY
     The getsockname() system call appeared in 4.2BSD.

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