GetBaseN

Function Usage

Obtains the baseN value generated by tiling computation.

Prototype

1
int32_t GetBaseN()

Parameters

None

Returns

baseN value generated by tiling computation.

Precautions

This API needs to be called using the created tiling object after the tiling computation (GetTiling) is complete.
