in thread open file descriptors

Well, in linux, you can do something like find

/proc/123/fd/ -type f | wc -l

FreeBSD doesn't have fd and osx doesn't even have /proc :(


Play that funky music white boy..

    Yeah I'm familiar with linux's proc filesystem (I love it, in fact), but this question is about writing a portable application. Also, I reallize that system calls are not necessarily portable from one O/S to another... that's why psuedo system calls as perl builtins are so nice. Like: I don't have to know what each O/S's system call is for deleting a file, but I know that in perl, unlink does the trick.
