View Ref-File13.8.2  OLGA-Client                                                TOS

An OLGA-Client is an application capable of editing objects used in 
other applications. Note that applications can be both Client and 
Server simultaneously; this doesn't cause problems and is highly 
desireable in most cases.

The following messages can be sent to or received from an OLGA-Client:

 ∙ OLGA_CLOSEDOC           Indicates closing of a document
 ∙ OLGA_GETINFO            Obtains index number for an Info file
 ∙ OLGA_LINK               Indicates inclusion of a file in a document
 ∙ OLGA_LINKBROKEN         Reference to an object is no longer 
                           available
 ∙ OLGA_LINKRENAMED        Reference to an object has been updated
 ∙ OLGA_OPENDOC            Registers document with Manager
 ∙ OLGA_RENAMELINK         Updates reference to an object
 ∙ OLGA_START              Launches Server for a Client in parallel
 ∙ OLGA_UPDATED            Server has altered a file
 ∙ OLGA_UNLINK             Terminates monitoring of a file
 ∙ OLGA_SERVERTERMINATED   Server has terminated

Warning: One has to point out here that in view of future operating 
system versions, memory regions used for communication between various 
programs or assigned via pointers have to be global (Mxalloc function 
with Global flag set). Otherwise, memory protection violation would 
occur if used on computers with PMMUs (e.g. Atari-TT030 or Falcon030).
