NAME    [Toc]    [Back]

       getpeername - get name of connected peer

SYNOPSIS    [Toc]    [Back]

       #include <sys/socket.h>

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

DESCRIPTION    [Toc]    [Back]

       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.

RETURN VALUE    [Toc]    [Back]

       On  success,  zero is returned.	On error, -1 is returned, and errno is
       set appropriately.

ERRORS    [Toc]    [Back]

       EBADF  The argument s is not a valid descriptor.

       ENOTSOCK    [Toc]    [Back]
	      The argument s is a file, not a socket.

       ENOTCONN    [Toc]    [Back]
	      The socket is not connected.

       ENOBUFS    [Toc]    [Back]
	      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.

CONFORMING TO    [Toc]    [Back]

       SVr4, 4.4BSD (the getpeername function call first appeared in  4.2BSD).

NOTE    [Toc]    [Back]

       The third argument of getpeername is in reality an `int *' (and this is
       what BSD 4.* and libc4 and libc5 have).	Some POSIX confusion  resulted
       in the present socklen_t.  The draft standard has not been adopted yet,
       but glibc2  already  follows  it  and  also  has  socklen_t.  See  also
