I recently discovered LD_PRELOAD, a cool environment variable that lets a library "intercept" system calls. For example, setting LD_PRELOAD to /usr/lib/libtsocks.so lets tsocks intercept socket connections and redirect them to a SOCKS proxy.
My question: how can I write a library that intercepts the gettimeofday() system call (or time() or whatever the 'date' command uses) and gets 'date' to return, say, "Thu Jan 1 00:00:00 UTC 1970"? I realize this involves a couple of steps (writing a C "library" for one), so any pointers are appreciated. My real intentions are more complex (and sinister <G>). -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
