# #hbUCPSetTaskDoneCb

`int32_t hbUCPSetTaskDoneCb(hbUCPTaskHandle_t taskHandle, hbUCPTaskDoneCb taskDoneCb, void *userdata);`

Register a callback function, this callback function is executed automatically after the task is completed.

- Parameter

  - [in] `taskHandle` Task handle pointer.
  - [in] `taskDoneCb` Callback function pointer.
  - [in] `userdata` User-defined data.

- Return Value

  - Return `0` means the API was successfully executed, otherwise the execution failed.

Note
This interface allows you to register a callback function that will be called to perform a user-defined function when the task is completed. If you don't need to customize the input, you can set userdata to nullptr. Please do not call `hbUCPReleaseTask`

to release the task in the callback function, otherwise undefined behavior may occur.
