7 These functions are the same as @code{printf}, @code{fprintf}, and
8 @code{sprintf}, respectively, except that they are called with a
9 @code{va_list} instead of a variable number of arguments. Note that
10 they do not call @code{va_end}; this is the application's
11 responsibility. In @libib{} they are implemented in terms of the
12 nonstandard but common function @code{_doprnt}.
