Manual Section... (2) - page: shutdown
NAMEshutdown - shut down part of a full-duplex connection
DESCRIPTIONThe shutdown() call causes all or part of a full-duplex connection on the socket associated with sockfd to be shut down. If how is SHUT_RD, further receptions will be disallowed. If how is SHUT_WR, further transmissions will be disallowed. If how is SHUT_RDWR, further receptions and transmissions will be disallowed.
RETURN VALUEOn success, zero is returned. On error, -1 is returned, and errno is set appropriately.
- sockfd is not a valid descriptor.
- The specified socket is not connected.
- sockfd is a file, not a socket.
