The FltGetIoPriorityHint routine is used by a minifilter driver to get IO priority information from Callback Data.
Data [in]A pointer to a FLT_CALLBACK_DATA structure that represents an I/O operation. This parameter is required and cannot be NULL.
The FltGetIoPriorityHint routine returns an IO priority hint retrieved from a FLT_CALLBACK_DATA structure.
The FltGetIoPriorityHint routine retrieves an IO Priority hint from the DataFLT_CALLBACK_DATA structure. This hint will be based on the following fields in the FLT_CALLBACK_DATA:
If these FLT_CALLBACK_DATA fields do not have an IO priority, the routine returns IoPriorityNormal.
