The setTexture() method of a MTLComputeCommandEncoder allows us to use nil as a parameter.
How can I check in the kernel function if the texture parameter is nil or not?
In the documentation I see there is a function called 'is_null_texture'. But the compiler does not know this function. I included already all the header files like <metal_stdlib>, <metal_texture>, <metal_relational>, <metal_common> hoping this would solve the problem.
Is this function maybe wrong in the documentation and has another syntax or does it not exist?
