How do I create the callback function? I haven't ever used a typedef'd
function before, and there isn't much info online.



Here are the declarations in canlib.h

typedef void (CANLIBAPI *kvCallback_t)(int handle, void* context, unsigned
int notifyEvent);

kvStatus CANLIBAPI kvSetNotifyCallback(int hnd, kvCallback_t callback, void*
context, unsigned int notifyFlags);

void CANLIBAPI
My_kvCallback(int handle, void* context, unsigned int notifyEvent)
{
whatever;
}
