I think the small change in centerHeadFoot, or probably better, in
set_runninghead_string, is exactly what's Paul is looking for, but he's
having trouble understanding what widechar is all about.
What about something like this? I haven't tested it.
=============================================================
transcriber.c, line 987:
=============================================================
int
truncate (widechar * char, int length, int max_length)
{
if (length <= max_length)
return length;
for (length = max_length; length > 0; length--)
if (char[length] == ' ')
return length;
return max_length;
}
void
set_runninghead_string (widechar * chars, int length)
{
ud->running_head_length = truncate (chars, length, ud->cells_per_line -
9);
memcpy (ud->running_head, chars, ud->running_head_length * CHARSIZE);
}
