bson_iter_key_len - Man Page

uint32_t
bson_iter_key_len (const bson_iter_t *iter);

• iter: A bson_iter_t.

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

An integer representing the key length.
