Detailed Description

An X11 Display connection wrapper.

This class is used to monitor multiple GLXPipe X11 display connections for events using a net::ConnectionSet.

For internal use only.

Member Function Documentation

virtual Notifier eq::X11Connection::getNotifier

(

)

const [inline, virtual]

Returns:

the notifier signaling events on the connection.

Reimplemented from eq::net::Connection.

Definition at line 55 of file X11Connection.h.

References eq::GLXPipe::getXDisplay().

Here is the call graph for this function:

virtual void eq::X11Connection::readNB	(	void *	buffer,
		const uint64_t	bytes
	)			[inline, protected, virtual]

Start a read operation on the connection.

This method is the low-level counterpart to recvNB().

This function returns immediately. The operation's Notifier will signal data availability, upon which readSync() should be used to finish the operation.

Parameters:

	buffer	the buffer receiving the data.
	bytes	the number of bytes to read.

See also:

readSync()

Implements eq::net::Connection.

Definition at line 64 of file X11Connection.h.

virtual int64_t eq::X11Connection::readSync	(	void *	buffer,
		const uint64_t	bytes
	)			[inline, protected, virtual]

Finish reading data from the connection.

This method is the low-level counterpart to recvSync(). It may return with a partial read.

Parameters:

	buffer	the buffer receiving the data.
	bytes	the number of bytes to read.

Returns:

the number of bytes read, or -1 upon error.

Implements eq::net::Connection.

Definition at line 66 of file X11Connection.h.

virtual int64_t eq::X11Connection::write	(	const void *	buffer,
		const uint64_t	bytes
	)			[inline, protected, virtual]

Write data to the connection.

Parameters:

	buffer	the buffer containing the message.
	bytes	the number of bytes to write.

Returns:

the number of bytes written, or -1 upon error.

Implements eq::net::Connection.
