The class synopses for classes codecvt<> (184.108.40.206) and codecvt_byname<> (220.127.116.11) say that the first parameter of the member functions length and do_length is of type const stateT&. The member function descriptions, however (18.104.22.168.1, paragraph 6; 22.214.171.124.2, paragraph 9) say that the type is stateT&. Either the synopsis or the summary must be changed.
If (as I believe) the member function descriptions are correct, then we must also add text saying how do_length changes its stateT argument.
In 126.96.36.199 [locale.codecvt], and also in 188.8.131.52 [locale.codecvt.byname], change the stateT argument type on both member length() and member do_length() from
In 184.108.40.206.2 [locale.codecvt.virtuals], add to the definition for member do_length a paragraph:
Effects: The effect on the state argument is ``as if'' it called do_in(state, from, from_end, from, to, to+max, to) for to pointing to a buffer of at least max elements.
