Do try man limit and man ulimit; well, my current installation has neither manpage, but at least ulimit's in /usr/bin by default. limit is a built-in command in some shells for the same purpose. As for soft/hard limits, ulimit -S vs. ulimit -H ought to do that. Incidentally, if you specify neither, both should get changed at the same time. csh is an excemption; here you need to use limit -h for hard limits. As for C programs, use getrlimit() and setrlimit() calls - but then you really ought to get the manpages, and I have no clue what this has to do with kernel hacking... *shakes head* ;)
