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().

RETURNS

       An integer representing the key length.

       SEE ALSO:
          bson_iter_key() to retrieve current key.
