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

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.

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.
