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.
