NAMEshutdown − shut down part of a full-duplex connection

---

LIBRARYStandard C library (libc, −lc)

---

SYNOPSIS#include <sys/socket.h>int shutdown(int sockfd, int how);

---

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 to indicate the error.

---

ERRORSEBADF  sockfd is not a valid file descriptor. EINVAL  An invalid value was specified in how (but see BUGS). ENOTCONN  The specified socket is not connected. ENOTSOCK  The file descriptor sockfd does not refer to a socket.

---

STANDARDSPOSIX.1-2001, POSIX.1-2008, 4.4BSD (shutdown() first appeared in 4.2BSD).

---

NOTESThe constants SHUT_RD, SHUT_WR, SHUT_RDWR have the value 0, 1, 2, respectively, and are defined in <sys/socket.h> since glibc-2.1.91.

---

BUGSChecks for the validity of how are done in domain-specific code, and before Linux 3.7 not all domains performed these checks. Most notably, UNIX domain sockets simply ignored invalid values. This problem was fixed for UNIX domain sockets in Linux 3.7.
