static void cmdFree	(	ITC_QueueItem *	qitem,
		unsigned int	status,
		FILE_Control *	ctl,
		void *	prm1,
		void *	prm2
	)			[static]

Free memory after sending ITC commands.

Parameters:

	qitem	The memory buffer.
	status	Status of command.
	ctl	FILE control structure.
	prm1	Completion callback paramter 1.
	prm2	Completion callback paramter 2.

WUT_cb_status FILE_uplDelay	(	SEM	sem,
		WUT_tmr *	timer
	)			[static]

Timer callback for file upload send delay.

Parameters:

	sem	The semaphore to release to indicate delay done.
	timer	The WUT handle for the timer.

Returns:

WUT_K_STATE_CHANGE_NO.

unsigned int FILE_UploadCancel	(	void *	prm,
		const struct _ITC_QueueItem *	qitem,
		void *	pay,
		unsigned int	len
	)

Callback function for the LFILUPLCANCEL command.

Passes the file upload cancel telecommand to the file upload state machine.

Parameters:

	prm	User context parameter
	qitem	Queue item
	pay	Payload pointer
	len	Payload length

Returns:

A FILE MSG code.

unsigned int FILE_UploadCommit	(	void *	prm,
		const struct _ITC_QueueItem *	qitem,
		void *	pay,
		unsigned int	len
	)

Callback function for the LFILUPLCOMMIT command.

After passing the file upload commit telecommand to the file upload state machine and verifying that the commit validation was successful, the requested file is created and the contents of the file upload buffer are written out.

Parameters:

	prm	User context parameter
	qitem	Queue item
	pay	Payload pointer
	len	Payload length

Returns:

A FILE MSG code.

unsigned int FILE_UploadData	(	void *	prm,
		const struct _ITC_QueueItem *	qitem,
		void *	pay,
		unsigned int	len
	)

Callback function for the LFILUPLDATA command.

Passes the file upload data telecommand to the file upload state machine.

Parameters:

	prm	User context parameter
	qitem	Queue item
	pay	Payload pointer
	len	Payload length

Returns:

A FILE MSG code.
