Hi there,

Perhaps anybody in here could help me since this is a plugin like question

I want to write a callback function for BASS_ChannelSetSync to run on Mac OS X from REALBasic 2008
This is my Call to BASS_ChannelSetSync

#if DebugBuild then
CONST dylibLocation = "@executable_path/../../../libbass.dylib"
CONST dylibLocation = "@executable_path/libbass.dylib"
Declare Function BASS_ChannelSetSync Lib dylibLocation (ByVal handle As Integer, ByVal type As Integer, ByVal param As Int64, Byval proc As Ptr, ByVal user As Integer) As Integer
resultI= BASS_ChannelSetSync(soundhandle,BASS_SYNC_POS,BASS_ChannelSeconds2Bytes(soundhandle, 5),AddressOf StopSyncCallback,0)

Which returns no error.

and this is my Definition of the callback function StopSyncCallback (declared in a module as public)
a as integer,b as integer,c as integer,d as integer
with no return type

What happens when its time to fire the callback, is that the RB IDE comes back to the foreground (as if there was a breakpoint) but when pressing resume repeatedly without any errors (the music keeps playing, as if the callback has finished its job) , I eventually get a Stack Overflow exception.

Anybody can see anything wrong with my code/setup, or has anybody done this already?
