SHUTDOWN(2) System Calls SHUTDOWN(2)
shutdown - shut down part of a full-duplex connection
int shutdown (int s, int how);
The shutdown call causes all or part of a full-duplex connection on the
socket associated with s to be shut down. If how is 0, further
receives will be disallowed. If how is 1, further sends will be disal-
lowed. If how is 2, further sends and receives will be disallowed.
A 0 is returned if the call succeeds, -1 if it fails.
The call succeeds unless:
EBADF S is not a valid descriptor.
S is a file, not a socket.
The specified socket is not connected.
The shutdown function call appeared in 4.2BSD.
