[filebuf.virtuals] Missing const-qualifiers in specification of overflow/underflow. #8256
Description
[filebuf.virtuals] contains the following code snippet for the specification of overflow:
charT* b = pbase();
charT* p = pptr();
charT* end;
char xbuf[XSIZE];
char* xbuf_end;
codecvt_base::result r =
a_codecvt.out(state, b, p, end, xbuf, xbuf+XSIZE, xbuf_end);This is missing a const on end because out takes the argument as const charT*&.
Similarly the specification of underflow contains:
char extern_buf[XSIZE];
char* extern_end;
charT intern_buf[ISIZE];
charT* intern_end;
codecvt_base::result r =
a_codecvt.in(state, extern_buf, extern_buf+XSIZE, extern_end,
intern_buf, intern_buf+ISIZE, intern_end);where a const is missing on extern_end.
I am not sure this can be handled as editorial, but at least the intention here seems obvious to me.
