NAME

       shutdown - shut down part of a full-duplex connection

SYNOPSIS

       shutdown(s, how)
       int s, how;

DESCRIPTION

       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, then fur-
       ther receives will be disallowed.  If how is 1, then further sends will be disallowed.  If how is 2, then further sends and  receives  will
       be disallowed.

DIAGNOSTICS

       A 0 is returned if the call succeeds, -1 if it fails.

ERRORS

       The call succeeds unless:

       [EBADF]	      S is not a valid descriptor.

       [ENOTSOCK]     S is a file, not a socket.

       [ENOTCONN]     The specified socket is not connected.

NAME

       shutdown - shut down part of a full-duplex connection

SYNOPSIS

       #include <sys/socket.h>

       int shutdown(int sockfd, int how);

DESCRIPTION

       The  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 VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS

       EBADF  sockfd is not a valid descriptor.

       ENOTCONN
	      The specified socket is not connected.

       ENOTSOCK
	      sockfd is a file, not a socket.

CONFORMING TO

       POSIX.1-2001, 4.4BSD (the shutdown() function call first appeared in 4.2BSD).

NOTES

       The 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.
