The WdfCommonBufferGetAlignedLogicalAddress method returns the logical address that is associated with a specified common buffer.
CommonBuffer [in]A handle to a common buffer object that the driver obtained by a previous call to WdfCommonBufferCreate.
WdfCommonBufferGetAlignedLogicalAddress returns the logical address of the buffer that is associated with the common buffer that the CommonBuffer parameter specifies.
A bug check occurs if the driver supplies an invalid object handle.
Logical addresses are mapped addresses that devices use to access physical memory.
If the driver called WdfDeviceSetAlignmentRequirement to set a buffer alignment requirement, the framework aligns the common buffer according to that alignment requirement.
