I've got several statements in my c code that i wish to surround by
#ifdefs and #endif.
Eg. The following code :
printf("This is debugging info: %d\n",i);
printf("This is some more debugging info: \n");
should become
#ifdef MACRO_NAME
printf("This is debugging info: %d\n",i);
printf("This is some more debugging info: \n");
#endif
So, all that i have to do is to write the macro name.
Is there a way to do this.
Thanks,

There might be proper included functionality for this already, but the
following solution seems to work reasonably well:
(defun ifdef-region (p1 p2)
(interactive "r")
(let* ((macro (read-from-minibuffer "Macro: "))
(ifdef (concat "#ifdef " macro "\n")))
(goto-char p1)
(beginning-of-line)
(insert ifdef)
(goto-char (+ p2 (length ifdef)))
(end-of-line)
(newline 1)
(insert "#endif")))

Look into <youremacsdir>/lisp/tempo.el file for how to set up such a template.

(define-skeleton my-c-conditionalize
"Conditionalize a piece of code with cpp stuff."
"CPP var to use: "
\n "#ifdef " str
\n _
\n "#endif /* " str " */" \n)
And then (using transient-mark-mode) select the region of code you want
to conditionalize and do M-x my-c-conditionalize RET MACRO_NAME RET
