The setting example for software
The sample code to register extended callback function that occurs at "input start interrupt" or "1 frame input
completion interrupt" or "input end interrupt" for ch2 is as follows.
<Sample code>
void CALLBACK CallbackFuncEx ( int nChannel, DWORD dwEvent, int nFrameNo, int nMemoryNo, void *
pParam)
{
DWORD Param = *((DWORD*)pParam);
printf( "CallbackFuncEx called. nChannel[%d] dwEvent[%d] nFrameNo[%d] nMemoryNo[%d]
*pParam[%d]¥n" , nChannel, dwEvent, nFrameNo, nMemoryNo, Param);
}
// Register extended callback function at main routine
int rtn;
int channel = 2;
// Plural specifications by
“OR”
DWORD dwEvent = ACL_INT_GRABSTART | ACL_INT_FRAMEEND | ACL_INT_GRABEND;
DWORD Param = 123456; // Parameter that gives at 5
th
argument
rtn = AcapRegistCallback(hDevice, channel, dwEvent, (EVENT_FUNC_EX)&CallbackFuncEx, ( void *)&Param);
// Input 5 frame
rtn = AcapGrabStart(hDevice, channel, 5);
// Use ACL_INT_GRABSTART at input start of each frame
// Use ACL_INT_FRAMEEND at input completion of each frame
// Callback function of ACL_GRABEND is called when 5 frame input is completed
<< Output result>> * If number of transfer destination memory = 3
CallbackFuncEx called. nChannel[2] dwEvent[1] nFrameNo[0] nMemoryNo[3] *pParam[123456] *Note

CallbackFuncEx called. nChannel[2] dwEvent[1] nFrameNo[4] nMemoryNo[1] *pParam[123456]
CallbackFuncEx called. nChannel[2] dwEvent[2] nFrameNo[5] nMemoryNo[2] *pParam[123456]
CallbackFuncEx called. nChannel[2] dwEvent[4] nFrameNo[5] nMemoryNo[2] *pParam[123456]
*Note
：
Since first GRABSTART interrupt does not input any frame, “0” is got for nFrameNo and number
of register memory (3) is got for nMemoryNo.
