GETPEERNAME(2)                       BSD                        GETPEERNAME(2)



NAME
     getpeername - get name of connected peer

SYNOPSIS
     getpeername(s, name, namelen)
     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.

ERRORS
     The call succeeds unless any of the following are true:

     [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.

DIAGNOSTICS
