Function set_desc_pointer_attr 

pub unsafe fn set_desc_pointer_attr(
    desc: cublasLtMatmulDesc_t,
    attr: cublasLtMatmulDescAttributes_t,
    ptr: *const c_void,
) -> Result<(), String>

Set a pointer-valued attribute on a matmul descriptor (used for BIAS_POINTER, EPILOGUE_AUX_POINTER, fp8 scale pointers).

Safety

desc must be a live cublasLtMatmulDesc_t; ptr must remain valid for the entire lifetime of any matmul call that uses desc.
