Using cJSON to read in a JSON array

Question

I am attempting to use the cJSON library, written by Dave Gamble, to read in the following JSON array:

\"items\": 
[
    {
        \"name\": \"command\",

If you want to run slightly faster, this is what the code looks like:

void parse_array(cJSON *array)
{
  cJSON *item = array ? array->child : 0;
  while (item)
  {
     cJSON *name = cJSON_GetObjectItem(item, "name");
     cJSON *index = cJSON_GetObjectItem(item, "index");
     cJSON *optional = cJSON_GetObjectItem(item, "optional"); 

     item=item->next;
  }
}

This avoids the O(n^2) cost that RBerteig correctly points out.

Call with:

parse_array(cJSON_GetObjectItem(cJSON_Parse(request_body),"items"));
