GETSOCKNAME(2)						     Linux Programmer's Manual						    GETSOCKNAME(2)

NAME

       getsockname - get socket name

SYNOPSIS

       #include <sys/socket.h>

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

DESCRIPTION

       Getsockname returns the current name for the specified socket.  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).

RETURN VALUE

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

ERRORS

       EBADF  The argument s is not a valid descriptor.

       ENOTSOCK
	      The argument s is a file, not a socket.

       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.

CONFORMING TO

       SVr4, 4.4BSD (the getsockname function call appeared in 4.2BSD).  SVr4 documents additional ENOMEM and ENOSR error codes.

NOTE

       The third argument of getsockname 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 accept(2).

NAME

       getpeername - get name of connected peer socket

SYNOPSIS

       #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 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.

RETURN VALUE

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

ERRORS

       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.
