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.
