GETSOCKNAME(2)

NAME
getsockname - get socket name

SYNOPSIS
#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
Zero 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)

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

HISTORY
The getsockname function call appeared in 4.2BSD.
