Fields

Name Value Description
NotSupported 0

The queried features are not supported.
Maybe 1

Only relevant to output protection (HDCP) subsystem queries. ProtectionCapabilities.IsTypeSupported is a synchronous, blocking call which is constrained to only block for very short periods (goal is < 100 milliseconds). As underlying HDCP establishment may take significantly longer than the blocking period, this Maybe result is returned while establishment is in progress. Once establishment succeeds or fails, the HDCP subsystem query will stabilize on Probably or NotSupported, respectively. As no event or promise mechanism is provided, the query must be repeated until NotSupported or Probably is returned.
Probably 2

The queried features are supported as of the time of the query. Display configurations can change dynamically, so Display subsystem and HDCP subsystem query results may become invalid after the query.
