What is the difference between OnCreateFileC and OnOpenFileC callback?

This is a single file system request divided into the two user mode callbacks based on the value of CreateDisposition parameter. Request is interpreted as OnCreateFileC callback when CreateDisposition is equal to CREATE_NEW, in other cases it is interpreted as OnOpenFileC callback. In both cases it is better to handle the callbacks identically, because a new file may be created with a CREATE_ALWAYS or TRUNCATE_EXISTING flag set as well.
