NAME

6       bson_iter_key_len - bson_iter_key_len()
7

SYNOPSIS

9          uint32_t
10          bson_iter_key_len (const bson_iter_t *iter);
11

PARAMETERS

13       ยท iter: A bson_iter_t.
14

DESCRIPTION

16       Fetches the length of the key for the current element observed by iter.
17       This is a constant time computation, and therefore faster than  calling
18       strlen() on a key returned by bson_iter_key().
19

SEE ALSO

21       bson_iter_key() to retrieve current key.
22

RETURNS

24       An integer representing the key length.
