void Ck::IO::open	(	string	name,
		CkCallback	opened,
		Options	opts
	)

Definition at line 406 of file ckio.C.

References Ck::IO::impl::director.

void Ck::IO::startSession	(	File	file,
		size_t	bytes,
		size_t	offset,
		CkCallback	ready,
		CkCallback	complete
	)

Prepare to write data into the file described by token, in the window defined by the offset and byte length.

When the session is set up, a SessionReadyMsg will be sent to the ready callback. When all of the data has been written and synced, a message will be sent to the complete callback.

void Ck::IO::startSession	(	File	file,
		size_t	bytes,
		size_t	offset,
		CkCallback	ready,
		const char *	commitData,
		size_t	commitBytes,
		size_t	commitOffset,
		CkCallback	complete
	)

Prepare to write data into.

• file, in the window defined by the
• offset and length in
• bytes. When the session is set up, a SessionReadyMsg will be sent to the
• ready callback. When all of the data has been written and synced, an additional write will be made to the file to `commit' the session's work. When that write has completed, a message will be sent to the
• complete callback.

void Ck::IO::write	(	Session	session,
		const char *	data,
		size_t	bytes,
		size_t	offset
	)

Write the given data into the file to which session is attached.

The offset is relative to the file as a whole, not to the session's offset.

Here is the caller graph for this function:

void Ck::IO::close	(	File	file,
		CkCallback	closed
	)

Close a previously-opened file.

All sessions on that file must have already signalled that they are complete.

Here is the caller graph for this function:

void Ck::IO::open	(	std::string	name,
		CkCallback	opened,
		Options	opts
	)

Open the named file on the selected subset of PEs, and send a FileReadyMsg to the opened callback when the system is ready to accept session requests on that file.

Note: The values in options are not currently a stable or working interface. Users should not set anything in them.
