GETPEERNAME(2)		  FreeBSD System Calls Manual		GETPEERNAME(2)

NAME
     getpeername -- get	name of	connected peer

LIBRARY
     Standard C	Library	(libc, -lc)

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

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

DESCRIPTION
     The getpeername() system call returns the name of the peer	connected to
     socket s.	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).  The	name is	truncated if the
     buffer provided is	too small.

RETURN VALUES
     The getpeername() 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.

     [ENOTCONN]		The socket is not connected.

     [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.
