BSON_ITER_KEY_LEN(3)		    libbson		  BSON_ITER_KEY_LEN(3)

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.
