getsockname - get socket name
int getsockname(int s, struct sockaddr *name, socklen_t *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).
On success, zero is returned. On error, -1 is returned, and errno is
EBADF The argument s is not a valid descriptor.
EFAULT The name parameter points to memory not in a valid part of the
process address space.
EINVAL namelen is invalid (e.g., is negative).
Insufficient resources were available in the system to perform
The argument s is a file, not a socket.
SVr4, 4.4BSD (the getsockname() function call appeared in 4.2BSD),
The third argument of getsockname() is in reality an int * (and this is
what 4.x BSD and libc4 and libc5 have). Some POSIX confusion resulted
in the present socklen_t, also used by glibc. See also accept(2).
