getsockname(2)

NAME
     getsockname - get socket name

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

     int getsockname (int s, struct sockaddr *name, int *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).

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.

     [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
     bind(2), socket(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 socket was explicitly bound to a pathname.
