C Specification

 XrResult xrThermalGetTemperatureTrendEXT(
     XrSession                                   session,
     XrPerfSettingsDomainEXT                     domain,
     XrPerfSettingsNotificationLevelEXT*         notificationLevel,
     float*                                      tempHeadroom,
     float*                                      tempSlope);

Allows to query the current temperature warning level of a domain, the remaining headroom and the trend.

Valid Usage (Implicit)

• The XR_EXT_thermal_query extension must be enabled prior to calling ThermalGetTemperatureTrendEXT
• session must be a valid XrSession handle
• domain must be a valid XrPerfSettingsDomainEXT value
• notificationLevel must be a pointer to an XrPerfSettingsNotificationLevelEXT value
• tempHeadroom must be a pointer to a float value
• tempSlope must be a pointer to a float value

Return Codes

On success, this command returns

• SUCCESS
• SESSION_LOSS_PENDING

On failure, this command returns

• ERROR_FUNCTION_UNSUPPORTED
• ERROR_VALIDATION_FAILURE
• ERROR_RUNTIME_FAILURE
• ERROR_HANDLE_INVALID
• ERROR_INSTANCE_LOST
• ERROR_SESSION_LOST

Parameters:

session - a valid XrSession handle.

domain - : the processing domain

notificationLevel - : the current warning level

tempHeadroom - : temperature headroom in degrees Celsius, expressing how far the most-critical temperature of the domain is from its thermal throttling threshold temperature.

tempSlope - : the current trend in degrees Celsius per second of the most critical temperature of the domain.
