array_cate(3) append subset of one array to another array


#include <array.h>

void array_cate(array* x,array* y, int64 pos,int64 stop);

  array x;
  array y;
  int64 pos;
  int64 stop;


array_cate is like array_cat, but uses only byte positions pos through stop-1 in y. It fails if pos negative, or if stop is smaller than pos, or if the number of initialized bytes in y is smaller than stop.
