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

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.

If successful, getsockname() returns 0; otherwise it returns −1 and sets errno to indicate the error.

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
