WdfDriverGetRegistryPath function

Description

[Applies to KMDF and UMDF]

The WdfDriverGetRegistryPath method retrieves the path to the driver's registry key in the registry's Services tree.

Parameters

Driver [in]

A handle to the driver's framework driver object, obtained by a previous call to WdfDriverCreate or WdfGetDriver.

Return value

WdfDriverGetRegistryPath returns a pointer to a NULL-terminated Unicode string that represents the driver's registry path. A system bug check occurs if the Driver handle is invalid.

Remarks

The registry path string that WdfDriverGetRegistryPath returns is obtained from the UNICODE_STRING structure that the driver received as input to its DriverEntry routine.

For more information about the registry, see Using the Registry in Framework-Based Drivers.
