UCM_PD_POWER_DATA_OBJECT_INIT_ULONG function

Description

Initializes a UCM_PD_POWER_DATA_OBJECT structure by interpreting Power Data Object values and sets each field correctly.

Parameters

Pdo [out]

A pointer to a UCM_PD_POWER_DATA_OBJECT structure.

UlongInLittleEndian [in]

The ULONG value to set in the Ul member of UCM_PD_POWER_DATA_OBJECT.

Remarks

A Power Data Object, as defined by the Power Delivery specification, is a 32-bit value. The hardware is expected to retrieve the Power Data Objects as 32-bit values. This utility function initializes a UCM_PD_POWER_DATA_OBJECT structure by interpreting those values and setting each field correctly.

The 4 byte value is expected to be in little-endian format. The structure is 4 bytes and the client driver can memcopy the Power Data Objects from the hardware into an array of UCM_PD_POWER_DATA_OBJECT structures.
