File-In-Session Scope

Applications can be very specific about the distribution of a message by specifying TT_FILE_IN_SESSION for the message scope. Only those applications that have joined both the file and the session indicated are considered potential recipients.

Applications can also scope a message to every client that has registered interest in the message's session by specifying TT_SESSION with tt_message_file_set for the message scope. When the message is received by a client whose pattern matches, the receiving client can get the file name by calling tt_message_file.

Example 8–3 Setting a File

Tt_message m= tt_message_create();
tt_message_scope_set(m, TT_FILE_IN_SESSION);
tt_message_file_set(m, file);

The first line creates message. The second line adds scope. The third line adds file to message scope.
