make_cudaPitchedPtr

Hi,
I see make_cudaPitchedPtr in some codes, but I cannot find it in cuda reference manual and programming guide. Where is the description about this function?

Thanks!

Im guessing its some kind of constructor for the struct, as with other make_* functions.

Struct is as follows:

struct cudaPitchedPtr {
void *ptr;
size_t pitch;
size_t xsize;
size_t ysize;
};
