hMap | ZMAP | A handle to a map variable, the mipmap resolution step factor of which is to be retrieved. |
An integer greater than one if mipmaps have been initialised. Otherwise, zero is returned.
As an example; if a value of 4 is returned by this function, it means that the first mipmap level that can be accessed by zmap_GetMipmapLevel is 4, the next is 16, after that is 64, and so on up to the maximum mipmap level given by zmap_GetMipmapMaxLevel.
