Hi,
Wondering how difficult it is to use c++ with BlitzMax.I have an application which is written in c++ and once compiled uses a flag to get it's input.The source uses
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>
#include <ctype.h>
#include <unistd.h>
#include <sys/time.h>

Any suggestions on how to integrate this apps functionality into my BlitzMax app ? Thanks in advance.

Check the manual under the Advance Topics section.
There you can find some sample code showing how to use c++ code with Bmax.

Well there's no way to directly call any c++ code from max. Anything you want max to interact with has to be wrapped in an a C function.

[code]
class CStuff
public:
CStuff(){
...
}
.
.
.
int DoThing(...){}
private:
DataType* someData;
};

extern "C"{
void* NewCStuff(){
CStuff* temp = new CStuff
return (void*)(temp)
}

int DoThingCStuff(void* myStuff, ...){
return (CStuff*)(myStuff)->DoThing(...)
}

}

I haven't used any C with max so I'm not 100% sure that's all correct, but it's a general idea at least.
