Syntax

​
Parameters

Type: XblContextHandle An xbox live context handle created with XblContextCreateHandle. xboxUserId   _In_
Type: uint64_t The XBOX User ID of the player. titleId   _In_
Type: uint32_t The title ID. serviceConfigurationId   _In_z_
Type: char* The Service Configuration ID (SCID) for the title. The SCID is considered case sensitive so paste it directly from the Partner Center. achievementId   _In_z_
Type: char* The UTF-8 encoded achievement ID as defined by XDP or Dev Center. percentComplete   _In_
Type: uint32_t The completion percentage of the achievement to indicate progress. Valid values are from 1 to 100. Set to 100 to unlock the achievement. Progress will be set by the server to the highest value sent. async   _In_
Type: XAsyncBlock* Caller allocated AsyncBlock.

​
Return value

Type: HRESULT HRESULT return code for this API operation.

​
Remarks

This API will work even when offline on PC and XBOX One. Offline updates will be posted by the system when connection is re-established even if the title isn’t running. The result of the asynchronous operation can be obtained by calling XAsyncGetStatus inside the AsyncBlock callback or after the AsyncBlock is complete. If this unexpectedly fails, ensure the SCID is correctly in the XblInitArgs as it is case-sensitive.
