      Well, if you know a little about your code formatting convention you can

      sed -n '/^main(/,/^}/p' foo.c

      which assumes "main(" will be at the start of a line and that the next
      closing } which is also at the start of a line is the end of the function.

      In general:

      sed -n '/starting-marker/,/ending-marker/p' filename...

      will do what you ask. You just have to pick suitable starting-marker and
      ending-marker patterns.

      Extremely handy. Cheers,
