disconnectx(2)

disconnects a connection on a socket

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.
