  Return values:

    - SANITIZER_SUCCESS – on success.

    - SANITIZER_ERROR_NOT_INITIALIZED – if unable to initialize the sanitizer.

    - SANITIZER_ERROR_INVALID_PARAMETER – if `enabled` is NULL, or if `subscriber`, `domain` or `cbid` is invalid.

SanitizerResult sanitizerIsInsideRecursiveCallback(

  uint32_t *isInside,

)

  Check if the current thread is inside a recursive Sanitizer callback.

  Returns whether the current thread is executing inside a nested (recursive) Sanitizer callback handler. This is useful for distinguishing between CUDA API calls made by the application versus calls made internally by Sanitizer itself during callback processing.

  This function tracks callback re-entrancy depth and returns true only when the depth is greater than 1, indicating that a Sanitizer callback has triggered another callback. It returns false for the initial (non-nested) callback level.

  Note

  Thread-safety: this function is thread safe.

  Parameters:

    isInside – Returns 1 if inside a recursive Sanitizer callback (depth > 1), 0 otherwise.

  Return values:

    - SANITIZER_SUCCESS – on success.

    - SANITIZER_ERROR_INVALID_PARAMETER – if `isInside` is NULL.

SanitizerResult sanitizerSubscribe(

  Sanitizer_SubscriberHandle *subscriber,
  Sanitizer_CallbackFunc callback,
  void *userdata,

)

  Initialize a callback subscriber with a callback function and user data.

  Initialize a callback subscriber with a callback function and (optionally) a pointer to user data. The returned subscriber handle can be used to enable and disable the callback for specific domains and callback IDs.

  Note

  Only one subscriber can be registered at a time.

  Note

  This function does not enable any callbacks.

  Note

  Thread-safety: this function is thread safe.

  Parameters:

    - subscriber – Returns handle to initialize subscriber.

    - callback – The callback function.

    - userdata – A pointer to user data. This data will be passed to the callback function via the `userdata` parameter.

  Return values:

    - SANITIZER_SUCCESS – on success.

    - SANITIZER_ERROR_NOT_INITIALIZED – if unable to initialize the sanitizer.

    - SANITIZER_ERROR_MAX_LIMIT_RACHED – if there is already a sanitizer subscriber.

    - SANITIZER_ERROR_INVALID_PARAMETER – if `subscriber` is NULL.

SanitizerResult sanitizerUnsubscribe(

  Sanitizer_SubscriberHandle subscriber,

)

  Unregister a callback subscriber.

  Removes a callback subscriber so that no future callback will be issued to that subscriber.

  Note

  Thread-safety: this function is thread safe.

  Parameters:

    subscriber – Handle to the initialized subscriber.

  Return values:

    - SANITIZER_SUCCESS – on success.

    - SANITIZER_ERROR_NOT_INITIALIZED – if unable to initialize the sanitizer.

    - SANITIZER_ERROR_INVALID_PARAMETER – if `subscriber` is NULL or not initialized.
