How do you set a "stack cookie?"

The title says it all. The GLU based demos in MiniGL require more stack space than the default on my system, so I thought that I'd add a stack cookie in order to ensure that they have enough stack. I just don't know how.

I would ask on utilitybase, but that site has been setting off avast antivirus recently, and is now listed as an attack site.

So, how is it done?

In the same way you'd set a version string, the stack cookie can be set like so:

static const char *__attribute__((used)) stack = "$STACK: 65535\0";

Just use the USED define in amiga-compiler.h which is
automatically included.

static USED const char *stack = "$STACK:65535";

Is \0 needed in the end of a string ?

No. The compiler does this automatically.

@colinw

Do DOS library scan for this cookie? and do it overwrite icon settings?

Yes, DOS uses it in RunCommand().
Workbench uses it too, and also the shell handler.

See; IDOS->FindSegmentStackSize() function.
