NAME
        VPrintf -- format and print string (buffered) (V36)

   SYNOPSIS
        count = VPrintf(fmt, argv)
          D0            D1   D2

        long vprintf(strptr, long *)

        count = Printf(fmt, ...)

        long printf(strptr, ...)

   FUNCTION
        Writes the formatted string and values to output().  this routine is
        assumed to handle all internal buffering so that the formatting string
        and resultant formatted values can be arbitrarily long.  Any secondary
        error code is returned in ioerr().  this routine is buffered.

        Note: rawdofmt assumes 16 bit ints, so you will usually need 'l's in
        your formats (ex: %ld versus %d).

   INPUTS
        fmt   - exec.library rawdofmt() style formatting string
        argv  - Pointer to array of formatting values

   RESULT
        count - Number of bytes written or -1 (EOF) for an error

   BUGS
        The prototype for Printf() currently forces you to cast the first
        varargs parameter to long due to a deficiency in the program
        that generates fds, prototypes, and amiga.lib stubs.
