shutdown − shut down part of a full-duplex connection
#include <sys/socket.h>
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 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.
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.
