SHUTDOWN(2)                         Linux Programmer's Manual                         SHUTDOWN(2)

       shutdown - shut down part of a full-duplex connection

       #include <sys/socket.h>

       int shutdown(int sockfd, int how);

       The  shutdown()  call causes all or part of a full-duplex connection on the socket associ-
       ated with sockfd to be shut down.  If how is SHUT_RD, further receptions  will  be  disal-
       lowed.  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.

       EBADF  sockfd is not a valid descriptor.

       EINVAL An invalid value was specified in how (but see BUGS).

              The specified socket is not connected.

              sockfd is a file, not a socket.

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

       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.

       As currently implemented, checks for the validity of how are done in domain-specific code,
       and not all domains perform these checks.  Most notably, UNIX domain sockets simply ignore
       invalid values; this may change in the future.

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/project-web/phpunixman/htdocs/index.php on line 306
