C++ (Cpp) codeV Examples

Example #1

File: boot.c Project: fmccabe/l-and-o

/*
 * This program is used to map special classes like integer into
 * L&O programs
 * This program is only safe before the first GC
 */

  memcpy(pc->data, cd, cdlen * sizeof(insWord));
  pc->arity = arity;
  return code;
}
