ADLINK PCI-8144 - Manual (Page 147)

Function Library 137
If TimeOut_ms is zero, the function tests the states of the spec-
ified objects and returns immediately. If TimeOut_ms is -1, the
function's time-out interval never elapses (infinate).
Return Values:
ERR_ParametersInvalid
ERR_DeviceNotInitial
ERR_ParametersInvalid
ERR_InterruptNotEnable
ERR_TimeOut
ERR_Win32Error
ERR_NoError
Example:
I32 factorInBits = 0x01; //Wait DI Ch0 falling
edge
ret = _8144_set_gpio_interrupt_factor( CardId,
factorInBits );
// wait single GPIO interrupt…
I32 TimeOutMs = 10000; //10 sec timeout
I16 GpioIntFactorBitNum = 0; //wait INT factor
bit number 0
ret = _8144_wait_single_gpio_interrupt( CardId,
GpioIntFactorBitNum, TimeOutMs );
if( ret == ERR_NoError ){
// Interrupt be triggered
}else{
//Timeout or wait failed
}
_8144_set_gpio_interrupt_factor( gCardId, 0 ); //
Disable GPIO interrupt
