>Description:
The meteor(4) man page includes 3 code examples for the 3 different modes of capture. The first two are complete and compile without any problems, but the third throws errors about undeclared variables.
I presume there is a line or two that was not correctly copied and pasted from the original source when preparing the man page.
Here's the output of 'gcc skeleton_capture_n.c'
In file included from skeleton_capture_n.c:5:

>How-To-Repeat:
Copy and paste the source from the section " 3. Memory mapped, multi-frame ring buffer synchronize capture." on the meteor(4) man page to a file; attempt to compile it.
>Fix:
Find the missing source lines. :)
