Im converting this code here

from this link http://dasl.mem.drexel.edu/~noahKuntz/openCVTut10.html

and in the code is a new operator id like to convert but i could use guidance how.

first of all i looked on google and there actually doesnt appear to   be a C new operator only C++ which is a little weird because the code at the above link is full of only OpenCV C functions so either there is a C new operator or the author is using C and C++ together. I was going to do foreign-alloc but at this link about the new operator for C++ it says
"Allocatescountbytes from free store. Calls the function pointer returned by std::get_new_handler on failure and repeats allocation attempts until new handler does not return or becomes a null pointer, at which time throws std::bad_alloc."

I dont really know what to make of that and that link is for C++...thus the reason for my question....any guidance is appreciated
