Detailed Description

Function Documentation

tiAckConnect()

int tiAckConnect	(	VOIDFUNCPTR	routine,
		unsigned int	arg
	)

Connect a user routine to be executed instead of the default TI interrupt/trigger latching acknowledge prescription.

Parameters

routine	Routine to call
arg	argument to pass to routine

Returns

OK if successful, otherwise ERROR

tiIntAck()

void tiIntAck

(

)

Acknowledge an interrupt or latched trigger. This "should" effectively release the "Busy" state of the TI.

Execute a user defined routine, if it is defined. Otherwise, use a default prescription.

tiIntConnect()

int tiIntConnect	(	unsigned int	vector,
		VOIDFUNCPTR	routine,
		unsigned int	arg
	)

Connect a user routine to the TI Interrupt or latched trigger, if polling.

Parameters

vector	VME Interrupt Vector
routine	Routine to call if block is available
arg	argument to pass to routine

Returns

OK if successful, otherwise ERROR

tiIntDisable()

void tiIntDisable

(

)

Disable interrupts or latching triggers.

tiIntDisconnect()

int tiIntDisconnect

(

)

Disable interrupts or kill the polling service thread.

Returns

OK if successful, otherwise ERROR

tiIntEnable()

int tiIntEnable

(

int

iflag

)

Enable interrupts or latching triggers (depending on set TI mode)

Parameters

iflag

if = 1, trigger counter will be reset
