C++ (Cpp) lookup_instruction Examples

Example #1

File: fl_exe_instructions.c Project: flon-io/flon

char flon_call_instruction(char dir, fdja_value *node, fdja_value *msg)
{
  char *inst = fdja_ls(node, "inst", NULL);

  fgaj_d("dir: %c, inst: %s", dir, inst);

  flon_instruction *i = lookup_instruction(dir, inst);

  char r = '?'; // 'unknown' for now

  if (i == NULL)
  {
    fdja_set(node, "status", fdja_s("failed"));
    push_error(node, "unknown instruction '%s'", inst, NULL);

    goto _over;
  }

  eval_catt_pre(dir, node, msg);

  remove_timer(dir, node, msg);

  r = i(node, msg);

  if (r == 'r') // error
  {
    fdja_set(node, "status", fdja_s("failed"));
    //fdja_set(node, "note", fdja_s("xxx")); // set by the instruction itself
  }

  eval_catt_post(dir, node, msg);

_over:

  free(inst);

  return r;
}
