Output to CLI

[REAKTOR BEAR]

I've read that "dos.lib" has a function to output text to CLI, but where can we find documentation or an example?

User starts demo from CLI.... CLI says: "Demo now loading..."
But how to do it?

dos/Printf() does that for you, from kick 2.0 onwards. Otherwise, for older kickstarts, you have to go through Output() to get the output handle, and Write() to send the characters manually, and you have to perform argument substitution manually as well.

If you like cryptic asm :P, example for KS1.x via _LVOutput() can be found here: http://eab.abime.net/showthread.php?t=106742&page=25

Easiest way is to open v36+ dos.library and call PutStr (unformatted) or VPrintf (formatted).

If 1.X compatibility is required it's still not too bad. Outputting a simple string:

        ; a6=dos.library
        jsr     _LVOOutput(a6)
        move.l  d0,d1 ; console output handle
        move.l  #msg,d2
        move.l  #msgend-msg,d3
        jsr     _LVOWrite(a6)
        ...
msg:    dc.b 'Demo now loading...'
msgend:

Or VPrintf replacement (beware of buffersize):

        ;d1=fmt,d2=args,a6=dos.library
buffersize=80
Printf:
        movem.l d2-d3/a2-a4,-(sp)
        move.l  a6,a4
        move.l  $4.w,a6
        move.l  d1,a0
        move.l  d2,a1
        lea     .storechar(pc),a2
        lea     -buffersize(a7),a7
        move.l  a7,a3
        jsr     _LVORawDoFmt(a6)
        move.l  a3,d2
        moveq   #-1,d3
.strlen:
        tst.b   (a3)+
        dbeq    d3,.strlen
        not.l   d3
        move.l  a4,a6
        jsr     _LVOOutput(a6)
        move.l  d0,d1
        jsr     _LVOWrite(a6)
        lea     buffersize(a7),a7
        movem.l (sp)+,d2-d3/a2-a4
        rts
.storechar:
        move.b  d0,(a3)+
        rts

Thanks a lot everyone, we will try the Thomas solution, it seems to be the simplest... "dos/Printf()" ... "and for older kickstarts Output() to get the output handle, and Write()"

What variable (D0,D1,D2) do we pass to doslib Output(), to optain the handle of the CLI window? is that: move.b "CON:",0,0 .. or something else?

Output returns the current output handle for the process - it takes no input. If the process was started by a CLI, and the output wasn't redirected, you will get the handle of the console..
