NAME

       getpeername - get name of connected peer

SYNOPSIS

       cc [ flag ... ] file ... -lsocket -lnsl [ library ... ]
       #include <sys/types.h>
       #include <sys/socket.h>

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

DESCRIPTION

       getpeername()  returns  the  name  of  the peer connected to socket s. The int pointed to by 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), prior to any  trun-
       cation. The name is truncated if the buffer provided is too small.

RETURN VALUES

       If successful, getpeername() returns  0; otherwise it returns  -1 and sets errno to indicate the error.

ERRORS

       The call succeeds unless:

       EBADF		       The argument s is not a valid descriptor.

       ENOMEM		       There was insufficient user memory for the operation to complete.

       ENOSR		       There were insufficient STREAMS resources available for the operation to complete.

       ENOTCONN 	       The socket is not connected.

       ENOTSOCK 	       The argument s is not a socket.
