NAME
disconnectx
—
disconnects a connection on a
socket
SYNOPSIS
#include
<sys/socket.h>
int
disconnectx
(int socket,
sae_associd_t associd, sae_connid_t
connid);
DESCRIPTION
The parameter socket is a socket. The
communication domain of the socket determines the availability and behavior
of
disconnectx
().
For connection-oriented socket, disconnectx
() is
analogous to shutdown(2) with SHUT_RDWR
issued on the
socket. For connectionless socket, it disassociates any existing association
to the peer socket.
The parameter associd specifies the
association identifier. It should be set to
SAE_ASSOCID_ANY
.
The parameter connid should be set to
SAE_CONNID_ANY
.
NOTES
disconnectx
()
is currently supported only on AF_INET and AF_INET6 sockets of type
SOCK_DGRAM and SOCK_STREAM.
RETURN VALUES
The disconnectx
() function returns the
value 0 if successful; otherwise the value of -1 is returned and the global
integer variable errno is set to indicate the
error.
ERRORS
The disconnectx
() system call succeeds
unless:
- [
EALREADY
] - Operation already in progress.
- [
EBADF
] - Socket is not a valid descriptor.
- [
EINVAL
] - The associd or connid argument is invalid or the underlying protocol is no longer attached to socket.
- [
ENOTCONN
] - The socket is not connected.
- [
ENOTSOCK
] - Socket is a file, not a socket.
