GETPEERNAME(2)                                                  GETPEERNAME(2)



NAME
     getpeername - get name of connected peer

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

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

NOTES
     ABI-compliant versions of the above call can be obtained from
     libsocket.so.

     This call does not return useful results when used on sockets of type
     AF_UNIX, unless the remote end was explicitly bound to a pathname.
