GETSOCKNAME(2)
NAME
getsockname − get socket name
USAGE
getsockname(s, name, namelen)
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 that name points to. On return, it contains the actual size of the name returned (in bytes).
RETURN VALUE
A zero 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 that isn’t in a valid part of the process address space.
