The HidD_GetPreparsedData routine returns a top-level collection's preparsed data.
HidDeviceObject [in]Specifies an open handle to a top-level collection.
PreparsedData [out]Pointer to the address of a routine-allocated buffer that contains a collection's preparsed data in a _HIDP_PREPARSED_DATA structure.
HidD_GetPreparsedData returns TRUE if it succeeds; otherwise, it returns FALSE. Use GetLastError to get extended error information.
Only user-mode applications can call HidD_GetPreparsedData. Kernel-mode drivers can use an IOCTL_HID_GET_COLLECTION_DESCRIPTOR request.
When an application no longer requires the preparsed data, it should call HidD_FreePreparsedData to free the preparsed data buffer.
