Function Documentation

Qnn_ErrorHandle_t QnnProfile_free(Qnn_ProfileHandle_t profile)

Free memory associated with the profile handle. All associated QnnProfile_EventId_t event handles are implicitly freed.

Parameters

profile – [in] Handle to be freed.

Returns

Error code

  • QNN_SUCCESS: No error encountered

  • QNN_PROFILE_ERROR_INVALID_HANDLE: profile is not a valid handle.

  • QNN_PROFILE_ERROR_MEM_ALLOC: error related to memory de-allocation

  • QNN_PROFILE_ERROR_HANDLE_IN_USE: profile is in-use and cannot be freed.

Note

Releasing the profile handle invalidates the memory returned via calls on this handle such as QnnProfile_getEvents(), QnnProfile_getSubEvents(), QnnProfile_getEventData(), QnnProfile_getExtendedEventData(), etc.

Note

The profile handle cannot be freed when it is bound to another API component or in use by an API call.

Note

Use corresponding API through QnnInterface_t.
