When running a babel C session under Linux/gcc I do not get any error
unless I add exit(0) as part of the C-code snippet. For some to me not
understood reason my program exits with error code=4, which is caught by
org-babel-eval and the printed output is not inserted into my buffer . I
solved this by adding `#include <stdlib.h>` and `exit(0);` as part of
org-babel-C-ensure-main-wrap .
Should I prepare this as patch?
Regards,
Dov

Oops. I sawthat I wrote "do not get any error" though I meant "do not get
any resulting output".

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,

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++ ;-).
