Member Function Documentation

◆ asyncConnect()

void isc::asiolink::UnixDomainSocket::asyncConnect	(	const std::string &	path,
		const ConnectHandler &	handler )

Asynchronously connects the socket to the specified endpoint.

Always returns immediately.

Parameters

path	Path to the unix socket to which we should connect.
handler	Callback to be invoked when connection is established or a connection error is signalled.

Asynchronously receives data over the socket.

Always returns immediately.

Parameters

[out]	data	Pointer to a location into which the read data should be stored.
	length	Length of the buffer.
	handler	Callback to be invoked when data have been received or an error is signalled.
