I second this proposal of publishing code wrt struct cmsghdr stuff.
The other day when I was feeling really depressed I decided to resolve the
mystery of passing file descriptors from one process to another via unix
domain sockets. Apart from these things mentioned in various books, there
weren't any examples. Moreover, there appear to be subtle differences between
4.3 and 4.4 based systems. It took me about a week to figure this out.
So - any takers for cmsghdr wizardry ?
