For now it's solved. =)

Hello. I can't understand how to use the native correctly.

/**
 * Retrieves data as number form in file under key and name.
 *
 * @param filename      The file location to search for the data.
 * @param key            The key within the file to look for. Set to "" for no key. Set to NFV_WILDCARD for any key.
 * @param name        The name under key to look for. Set to NFV_WILDCARD for any name.
 * @param identifier        The character used to identify different keys.
 * @param key_tell_start    Where to start searching for key.
 * @param key_tell_find  Where the key was found.
 * @param name_tell_start   Where to start searching for name.
 * @param name_tell_find    Where the name was found.
 * @param key_copy      The string that will contain the key of the data retrieved. Only used with NFV_WILDCARD for key.
 * @param key_len         If specified, the size of the key found to copy. Only used with NFV_WILDCARD for key.
 * @param name_copy   The string that will contain the name of the data retrieved. Only used with NFV_WILDCARD for name.
 * @param name_len      If specified, the size of the name found to copy. Only used with NFV_WILDCARD for name.
 * @return          Numeric value of data found. 0 if no data.

nfv_get_num(const filename[], const key[], name[], const identifier=';', const key_tell_start=0, &key_tell_find=0, const name_tell_start=0, &name_tell_find=0, key_copy[]="", const key_len=0, name_copy[]="", const name_len=0)

Tried many times.. but no success.
