GETPEERNAME(2)		    BSD System Calls Manual		GETPEERNAME(2)

     getpeername — get name of connected peer

     Standard C Library (libc, -lc)

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

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

     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 buf‐
     fer provided is too small.

     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.

     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.

     accept(2), bind(2), getsockname(2), socket(2)

     The getpeername() system call appeared in 4.2BSD.
