Description

Param1

The pin ID originating the event

Param2

A pointer to a "CAM_NOTIFICATION_CONTEXT", which contains the size of the structure, an hresult, and the picture ID.

If the attempt to allocate memory for the camera notification context does not succeed, Param2 will be NULL. The application must check the pointer to determine if it is valid before dereferencing it.
