GETPEERNAME(1)						      General Commands Manual						    GETPEERNAME(1)

NAME

       getpeername - get name of connected TCP/IP peer

SYNOPSIS

       getpeername [-n] [-p protocol]

DESCRIPTION

       getpeername  prints  the  IP address and service name (port number) of the remote peer connected to standard input.  The IP address and the
       service name are printed on the same line, separated by one space.

OPTIONS

       -n     Don't translate IP addresses and port numbers to names.

       -p protocol
	      Force getpeername to use protocol as the protocol when translating port numbers to service names.  Protocol  can	be  tcp  and  udp.
	      Normally, getpeername automatically determines what type of socket it is connected to.

SEE ALSO

       getpeername(3).

BUGS

       Only works on IP sockets.

NAME

     getpeername -- get name of connected peer

SYNOPSIS

     #include <sys/socket.h>

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

DESCRIPTION

     Getpeername() returns the name of the peer connected to socket s.	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).	The name is truncated if the buffer pro-
     vided is too small.

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.

     [ENOTCONN] 	The socket is not connected.

     [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.
