+@deftypefnx Supplemental int vfprintf (FILE *@var{stream}, const char *@var{format}, va_list @var{ap})
+@deftypefnx Supplemental int vsprintf (char *@var{str}, const char *@var{format}, va_list @var{ap})
+
+These functions are the same as @code{printf}, @code{fprintf}, and
+@code{sprintf}, respectively, except that they are called with a
+@code{va_list} instead of a variable number of arguments.  Note that
+they do not call @code{va_end}; this is the application's
+responsibility.  In @libib{} they are implemented in terms of the
+nonstandard but common function @code{_doprnt}.
