Calling Sequence

int n, vprintf();
vastart(ap);
n = vprintf(format, ap);
vaend(ap);
Description
The vprintf function allows you to print a variable argument list
to the standard output file. It is similar to printf, except
that instead of passing arguments after the format string
directly to the function, you pass the argument pointer that is
set up with va_start (see "The varargs.h Include File" in Chapter
1). See the "Input/Output Functions and Macros" section of
Chapter 1 for buffering information on I/O functions and macros.
Returns
The vprintf function returns a negative value on error.
