I want to get the first key and value at some sections, but i don't know his keyname so kv.GetString seems not work. Is there another way to get both of them use someting like index?

something like this:

PHP Code:

if(KvGotoFirstSubKey(kv, false)) do
{
    KvGetSectionName(kv, key, sizeof(key));
    KvGetString(kv, NULL_STRING, value, sizeof(value));
} while(KvGotoNextKey(kv, false));

no, your can't go to the first subkey actually when only have key - value in one section.
I test a kv like that and in section A if you want to use GoToFirstSubkey, it return false. Only can get the value in section A by using a known key and use GetString(key, ...).

"root"
{
    "A"
    {
         "key"  "value"
         "key"  "value"
         "key"  "value"
         "key"  "value"
    }
}

I solve my problem in a not perfect way.
Since the key is custom, i have to store it like:

"root"
{
    "A"
    {
         "key"
          {
             "key"  "value"
          }
         "key"
          {
             "key"  "value"
          }
         "key"
          {
             "key"  "value"
          }
         "key"
          {
             "key"  "value"
          }
         "key"
          {
             "key"  "value"
          }
    }
}

If you create your own custom sort, you will know exactly which position said key is always in, and can immediately call it without cycling through all the keys and sub keys. This is great for two reasons: quick lookups and guarantees a linear time complexity.
