disconnectx(2) BSD System Calls Manual disconnectx(2)
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 connec-
tion-oriented socket, disconnectx() is analogous to shutdown(2) with
SHUT_RDWR issued on the socket. For connectionless socket, it disassoci-
ates 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.
