Type Alias EfCudaMapFnNullable 

pub type EfCudaMapFnNullable = Option<unsafe extern "C" fn(ctx: *const c_void, resource: *mut c_void, out_ptr: *mut *mut c_void, out_len: *mut usize) -> c_int>;

Map a CUDA graphics resource to a device pointer. 0 on success.

May be NULL where an entry point takes one; such an entry point refuses a NULL rather than calling through it.
