5.3 Create a User Interrupt Function

The programmer must first write a user interrupt function. This function must have a void return value, and a single void parameter. This is for WinDriver compatibility. It is not possible to pass parameters into the user interrupt function. When the user's function is called, the void parameter will always be NULL (0). The function below is a sample function that will simply increment a global counter variable.

void MyUserInterruptFunction(void* param)
{
    counter++;
}
