Where is stdlib.h?

In GameStudio Manual there some examples about engine_open, engine_close etc.
In the examples I can see this line: #include <stdlib.h>
What is the folder where from this header is pulled in?

Hey!

As far as I know, it's a standard library in C. And those engine_open, engine_close, etc functions are SDK functions.

Edit: maybe I misunderstood your question. If you want to find the <stdlib.h> I guess you should check your IDE (f.e. visual studio) or C compiler.

Best regards!

Those examples are for c++ engine sdk and not lite-c.

Thanks two of you guys.
Really, I should think that belongs to sdk.
