shutdown - shut down socket send and receive operations
Návod, kniha: POSIX Programmer's Manual
#include <sys/socket.h>
int shutdown(int
socket, int
how );
The
shutdown() function shall cause all or part of a full-duplex
connection on the socket associated with the file descriptor
socket to
be shut down.
The
shutdown() function takes the following arguments:
- socket
- Specifies the file descriptor of the socket.
- how
- Specifies the type of shutdown. The values are as
follows:
- SHUT_RD
Disables further receive operations.
- SHUT_WR
Disables further send operations.
- SHUT_RDWR
Disables further send and receive
operations.
The
shutdown() function disables subsequent send and/or receive
operations on a socket, depending on the value of the
how argument.
Upon successful completion,
shutdown() shall return 0; otherwise, -1
shall be returned and
errno set to indicate the error.
The
shutdown() function shall fail if:
- EBADF
- The socket argument is not a valid file
descriptor.
- EINVAL
- The how argument is invalid.
- ENOTCONN
- The socket is not connected.
- ENOTSOCK
- The socket argument does not refer to a socket.
The
shutdown() function may fail if:
- ENOBUFS
- Insufficient resources were available in the system to
perform the operation.
