DCx Camera Functional Description and SDK Manual
4.3.62 is_InitEvent
Syntax
INT is_InitEvent (HIDS hCam, HANDLE hEv, INT which)
Description
is_InitEvent() initializes the event handle for the specified event object. This registers the event
object in the uc480 kernel driver.
Attention
Using USB cameras under Windows
The following events require a Windows message loop. This message loop has to be executed by
the thread that loads the uc480 API. The message loop is usually provided by the application
window. In some cases, the message loop might not be created automatically (e.g. in console
applications). In this case you will need to implement the message loop yourself.
This applies to the following uc480 events:
IS_SET_EVENT_REMOVE
IS_SET_EVENT_REMOVAL
IS_SET_EVENT_DEVICE_RECONNECTED
IS_SET_EVENT_NEW_DEVICE
If no message loop exists, a USB camera will not be automatically detected after reconnecting.
Input parameters
Event handle created by the CreateEvent()
Windows API function.
ID of the event to be initialized (see
is_EnableEvent())
Return values
One of the submitted parameters is outside the
valid range or is not supported for this sensor or
is not available in this mode.
