For example, imagine you had a library which factored large composite numbers. Typically, it might have a C interface--say, a function called `int *factorize(int bignum)`. With FUSD, it's possible to create a device file interface--say, a device called `/dev/factorize` to which clients can `write(2)` a big number, then `read(2)` back its factors. -* This may sound strange, but device file APIs have at least three advantages over a typical library API. First, it becomes much more language independent--any language that can make system calls can access the factorization library. Second, the factorization code is running in a different address space; if it crashes, it won't crash or corrupt the caller. Third, and most interestingly, it is possible to use `select(2)` to wait for the factorization to complete. `select(2)` would make it easy for a client to factor a large number while remaining responsive to other events that might happen in the meantime. In other words, FUSD allows normal user-space libraries to integrate seamlessly with UNIX's existing, POSIX-standard event notification interface: `select(2)`." +* This may sound strange, but device file APIs have at least three advantages + over a typical library API.
