How to Call a "C" Program

Hi,

I need some help as I want to invoke an external “C” program from Smalltalk.

Could someone let me know how I would go about this? I am currently using VW3.0 if that matters.

Thanks !

Michael,

There is a component called DLL & C Connect which is well documented.

Michael,

DLLCC is useful for calling a function that exists inside a DLL (on windows) or inside an ".so" file (on unix). If you are trying to just invoke a program, you can go do a callout to the operating system. Under Unix, you use the #cshOne: method in the UnixProcess class. If you want to run the command "startMyProgram", you'd say:

"UnixProcess cshOne: startMyProgram".

And if you upgrade to vw7.4, you don't have to use the heinous csh anymore. You can just use shOne:
