GETSOCKNAME(2)

NAME
getsockname - get socket name

LIBRARY
libc

SYNOPSIS
#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 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 VALUES

ERRORS
The call succeeds unless:

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

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

[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), getpeername(2), socket(2)

HISTORY
The getsockname() function call appeared in 4.2BSD.

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