Summary

0001108: Implement flock

Description

I've ported H. Peter Anvin's flock implementation (http://directory.fsf.org/All/flock.html) [^] to BusyBox. This utility is handy for implementing mutual exclusion in shell scripts.

The attached patch is a rough first draft. It works, but segfaults if the fd# argument is missing. I would appreciate suggestions for improvements, especially for making option processing and usage more BusyBox-like.

Notes
(0001851) eswierk 12-01-06 11:58	I just noticed that my Fedora system has another implementation of flock, from util-linux. The usage is completely different from the hpa implementation, and since it's probably in much more widespread usage, I'll port this one to BusyBox instead.
