Parameters
xblContextHandle   _In_Type: XblContextHandle XBOX services context for the local user. permissionToCheck   _In_
Type: XblPermission The permission to check. targetXuid   _In_
Type: uint64_t The target user’s Xuid for validation. async   _In_
Type: XAsyncBlock* The AsyncBlock for this operation.
Return value
Type: HRESULT Returns S_OK if the request started. S_OK doesn’t mean that permission was granted or that the operation is complete. Possible error codes include the following. This list isn’t exhaustive.Remarks
If multiple permissions and/or target users are needed, use the batch API instead: XblPrivacyBatchCheckPermissionAsync Call XblPrivacyCheckPermissionResultSize and XblPrivacyCheckPermissionResult upon completion to get the result. If the operation fails,XblPrivacyCheckPermissionResultSize and XblPrivacyCheckPermissionResult return the failure HRESULT. Pass that HRESULT to XblGetErrorCondition to classify it. A failed request is different from a successful result in which isAllowed is false, but in both cases block the action that permissionToCheck protects. If the condition is XblErrorCondition::Http429TooManyRequests, the service is throttling your title. Wait before you try again, and limit how often you retry.
