Prototype of user-provided callback function for copying the specified number of bytes from one memory location to another.
#include "huctx.h"
typedef void hu_MemCpyFunc(void *dst, const void *src, size_t len, void *cbData);
BlackBerry 10.0.0
The library will not call this function with overlapping areas (i.e., there is no need to worry about overlapping memory areas).
The cbData argument is initialized during global context creation and will be passed to this function.
