shutdown(2)                System Calls Manual               shutdown(2)

ИМЯ

       shutdown - shut down part of a full-duplex connection

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <sys/socket.h>

       int shutdown(int sockfd, int how);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, zero is returned.  On error, -1 is returned, and
       errno is set to indicate the error.

ОШИБКИ

       EBADF  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.

СТАНДАРТЫ

       POSIX.1-2008.

ИСТОРИЯ

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

ПРИМЕЧАНИЯ

       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.

ОШИБКИ

       Checks 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.
