Members

omac

ConfigureType

A GUID that specifies the command. For a list of values, see Content Protection Commands.

hChannel

A handle to the authenticated channel. To get the handle, call IDirect3DDevice9Video::CreateAuthenticatedChannel.

SequenceNumber

The query sequence number. At the start of the session, generate a cryptographically secure 32-bit random number to use as the starting sequence number. For each command, increment the sequence number by 1.
