NAME

       bson_iter_key_len - bson_iter_key_len()

SYNOPSIS

          uint32_t
          bson_iter_key_len (const bson_iter_t *iter);

PARAMETERS

       · iter: A bson_iter_t.

DESCRIPTION

       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().

SEE ALSO

       bson_iter_key() to retrieve current key.

RETURNS

       An integer representing the key length.
