acltdtGetBufUserData

The Atlas Training Series Product does not support this API.

Obtains the data in the user data area of the shared buffer, and copies the data to the buffer allocated by the user with offset.

The default size of the shared buffer is 96 bytes. The sum of offset and size must be less than or equal to 96 bytes. Otherwise, an error is returned.
For the Atlas 200/300/500 Inference Product, this API can be used only in the following modes:
