@(#)getsockname.2 6.2 (Berkeley) 02/14/89

C 5 getsockname - get socket name

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

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). A 0 is returned if the call succeeds, -1 if it fails. The call succeeds unless:

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

15 [ENOTSOCK] The argument s is a file, not a socket.

15 [ENOBUFS] Insufficient resources were available in the system to perform the operation.

15 [EFAULT] The name parameter points to memory not in a valid part of the process address space.

bind(2), socket(2) Names bound to sockets in the UNIX domain are inaccessible; getsockname returns a zero length name.
