C Specification

The xrSyncActions function is defined as:

XrResult xrSyncActions(
    XrSession                                   session,
    const XrActionsSyncInfo*                    syncInfo);

Parameters

Parameter Descriptions
  • session is a handle to the XrSession that all provided action set handles belong to.

  • syncInfo is an XrActionsSyncInfo providing information to synchronize action states.

Description

xrSyncActions updates the current state of input actions. Repeated input action state queries between subsequent synchronization calls must return the same values. The XrActionSet structures referenced in the syncInfo.activeActionSets must have been previously attached to the session via xrAttachSessionActionSets. If any action sets not attached to this session are passed to xrSyncActions it must return XR_ERROR_ACTIONSET_NOT_ATTACHED. Subsets of the bound action sets can be synchronized in order to control which actions are seen as active.

If session is not focused, the runtime must return XR_SESSION_NOT_FOCUSED, and all action states in the session must be inactive.
