getsockname(3SOCKET)					     Sockets Library Functions					      getsockname(3SOCKET)

NAME

       getsockname - get socket name

SYNOPSIS

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

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

DESCRIPTION

       getsockname() returns the current name for 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 in bytes of the name returned.

RETURN VALUES

       If successful, getsockname() 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 file descriptor.

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

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

       ENOTSOCK    The argument s is not a socket.

NAME

     getsockname -- get socket name

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/socket.h>

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

DESCRIPTION

     The getsockname() system call returns the current name for the specified socket.  The namelen argument 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 VALUES

     The getsockname() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
     indicate the error.

ERRORS

     The call succeeds unless:

     [EBADF]		The argument s is not a valid descriptor.

     [ECONNRESET]	The connection has been reset by the peer.

     [EINVAL]		The value of the namelen argument is not valid.

     [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 argument points to memory not in a valid part of the process address space.

SEE ALSO

     bind(2), getpeername(2), socket(2)

HISTORY

     The getsockname() system call appeared in 4.2BSD.

BUGS

     Names bound to sockets in the UNIX domain are inaccessible; getsockname() returns a zero length name.
