DESCRIPTION

14       The tcp_pageout() function pages out the ZSock data area into segment 1
15       (addresses 16384-32767) of the z88s memory map.
16
17       The  parameter  oldbinding  is  the   return   value   from   a   prior
18       tcp_pagein(3z) function.
19
20       This  function  is  primarily  of  use  to  daemons which use the ZSock
21       dataarea for small amounts of storage.

RETURN VALUE

25       tcp_pagein() returns the previous binding of segment 1 which should  be
26       used as a parameter to tcp_pageout(3z)
