Using sysread(), your indication that the other end
has closed the connection would be a "successful sysread

value of sysread() for undef (error) and zero( end of
file, a.k.a, client closed connection ).
In the event that something unusual happens ( perhaps
the client crashed ?), keepalives could be helpful.
