A.7 Receive Events
The following sample codes show how to configure the frame grabber event, how to register event
callback, and how to handle the event information received in the callback function.
#include <Windows.h>
#include <conio.h>
#include <stdio.h>
#include <process.h>
#include "MVFGControl.h"
bool g_bExit = FALSE;
#define BUFFER_NUMBER
3
// Number of requested buffers
void __stdcall EventCallBack(MV_FG_EVENT_INFO* pstEventInfo, void* pUser)
