BlockDev_Command_Complete

The BlockDev_Command_Complete service calls the callback procedure specified in the BlockDev_Device_Descriptor structure. After the callback procedure returns, BlockDev_Command_Complete sends the pending command (if any) to the block device's command procedure. The service sends pending commands only if the BDF_Serial_Cmd flag is set in the BDD_Flags field. This field is located in the device's BlockDev_Device_Descriptor structure.

A block device driver should call this service whenever it completes a command.

Parameters

bdd

Points to the BlockDev_Device_Descriptor structure containing information about the block device.

Return Value

Comments
