sendfile on various systems?

[Georg Schwarz <georg.schwarz%freenet.de@localhost>]

On Linux, sendfile() looka like this:

ssize_t sendfile(int out_fd, int in_fd, off_t *offset, size_t count)

On MacOS X it looks like this:

int
     sendfile(int fd, int s, off_t offset, off_t *len, struct sf_hdtr *hdtr,
         int flags)

what about other systems?

What's best practice of handling (probably Linux-originated) code that uses 
sendfile?
Should sendfile support best be disabled in systems other than Linux? (the code 
already has useful #ifdefs included)
