Re: [O] org-babel-C-ensure-main-wrap fails unless I add exit(0)

Sure. They should be equivalent. (In C++ return is prefered as it calls destructors. But anyone relying on this when using C++ in org-mode should imnsho get a permanent ban from ever using C/C++ ;-).

Would this alternate version work (without requiring stdlib.h)?

(defun org-babel-C-ensure-main-wrap (body)
 "Wrap body in a \"main\" function call if none exists."
 (if (string-match "^[ \t]*[intvod]+[ \t\n\r]*main[ \t]*(.*)" body)
     body
   (format "int main() {\n%s\nreturn(0);\n}\n" body)))

Thanks,
