How to use Playsid.library in assembly?

[kamelito]

Hi
Is there somewhere a bit of code that show how to load, play and stop a 64 tune using Playsid.library in assembly?

Without error-checks etc.

    include ndk32/lvo/exec_lib.i
    include playsid/playsid_lib.i

    macro execall
    move.l      4, a6
    jsr         (_LVO\1, a6)
    endm


    section code

    moveq       #0, d0
    lea         playsidlib, a1
    execall     OpenLibrary
    move.l      d0, _PlaySidBase

    CALLPLAYSID AllocEmulResource

    moveq       #50, d0
    CALLPLAYSID SetVertFreq

    lea         sidmodule, a0 
    move.l      a0, a1
    move.l      #sidlength, d0
    CALLPLAYSID SetModule

    moveq       #0, d0
    CALLPLAYSID StartSong

.w  btst        #6, $bfe001
    bne         .w

    CALLPLAYSID StopSong
    CALLPLAYSID FreeEmulResource

    move.l      _PlaySidBase, a1
    execall     CloseLibrary

    moveq       #0, d0
    rts


playsidlib
    dc.b "playsid.library", 0
    even
sidmodule
    incbin trifle.sid
sidlength = *-sidmodule


    section data

_PlaySidBase
    ds.l 1
