Call host program procedure from DLL?

[wombats]

Hi,

Is it possible to call a procedure in the host/main program from a DLL, both of which were programmed in PB?

Thanks.

Use a passed pointer reference and a prototype.

I don't really know how to do that. What am I doing wrong? I get Invalid Memory Access when trying to pass the procedure.

Code: Select all

Procedure MyFunction(param.i)
  Debug param
EndProcedure

Prototype InitLib(*func)
Prototype LibFunc(param.i)

OpenLibrary(0, "test.dylib")

Global InitLib.InitLib = GetFunction(0, "Init")
Global LibFunc.LibFunc = GetFunction(0, "Func1")

InitLib(@MyFunction())
LibFunc(5)

Library

Code: Select all

Prototype HostFunc(param1.i)

Global HostFunc.HostFunc

Procedure Init(*func)
  HostFunc = *func
EndProcedure

Procedure Func1(param1.i)
  HostFunc(param1)
EndProcedure

Try ProcedureDLL

Oops, stupid oversight.
