sendfile ?pos ?len ~fd sock sends mmap-able data from file
descriptor fd to socket sock using offset pos and length len.
Raises Unix_error on Unix-errors.
Returns the number of characters actually written.
NOTE: if the returned value is unequal to what was requested (=
the initial size of the data by default), the system call may have
been interrupted by a signal, the source file may have been truncated
during operation, or a timeout occurred on the socket during sending.
It is currently impossible to find out which of the events above
happened. Calling Linux_ext.sendfile several times on the same descriptor
that only partially accepted data due to a timeout will eventually
lead to the unix error EAGAIN.

val pr_set_pdeathsig : Signal.t -> unit
pr_set_pdeathsig s sets the signal s to be sent to the executing
process when its parent dies. NOTE: the parent may have died
before or while executing this system call. To make sure that you
do not miss this event, you should call Unix.getppid to get
the parent process id after this system call. If the parent has
died, the returned parent PID will be 1, i.e. the init process will
have adopted the child. You should then either send the signal to
yourself using Unix.kill, or execute an appropriate handler.
val pr_get_pdeathsig : unit -> Signal.tpr_get_pdeathsig () get the signal that will be sent to the
currently executing process when its parent dies.val file_descr_realpath : Unix.file_descr -> string
file_descr_realpath fd
Raises Unix_error on errors.
Returns the canonicalized absolute
pathname of the file associated with file descriptor fd.
