Expand description

fallocate(fd, mode, offset, len)—Adjusts file allocation.

This is a more general form of posix_fallocate, adding a mode argument which modifies the behavior. On platforms which only support posix_fallocate and not the more general form, no FallocateFlags values are defined so it will always be empty.
