<Title>DESCRIPTION</Title>
|
|
<Para>The
|
|
<Function>ttdt_Get_Modified</Function> function
|
|
sends a
|
|
<Symbol Role="Message">Get_Modified</Symbol> request in the scope
|
|
<Emphasis>the_scope</Emphasis> and waits for the reply.
|
|
A
|
|
<Symbol Role="Message">Get_Modified</Symbol> request asks if any ToolTalk client has
|
|
changes pending on
|
|
<Symbol Role="Variable">pathname</Symbol> that it intends to make persistent.
|
|
</Para>
|
|
<Para>The
|
|
<Symbol Role="Variable">context</Symbol> argument describes the environment to use.
|
|
If
|
|
<Symbol Role="Variable">context</Symbol> is not zero, messages created by
|
|
<Function>ttdt_Get_Modified</Function> inherit from
|
|
<Symbol Role="Variable">context</Symbol> all contexts whose slotname begins with the characters
|
|
<SystemItem Class="Constant">ENV_</SystemItem>. That is, the environment described in
|
|
<Symbol Role="Variable">context</Symbol> is propagated to messages created by
|
|
<Function>ttdt_Get_Modified</Function>.</Para>
|
|
<Para>The
|
|
<Symbol Role="Variable">pathname</Symbol> argument is a pointer to a pathname
|
|
on which the client is operating.
|
|
</Para>
|
|
<Para>The
|
|
<Emphasis>the_scope</Emphasis> argument identifies the scope of the request.
|
|
If
|
|
<Emphasis>the_scope</Emphasis> is
|
|
<SystemItem Class="Constant">TT_SCOPE_NONE</SystemItem>, <Function>ttdt_Get_Modified</Function> tries
|
|
<SystemItem Class="Constant">TT_BOTH</SystemItem>, and falls back to
|
|
<SystemItem Class="Constant">TT_FILE_IN_SESSION</SystemItem> if, for example,
|
|
the ToolTalk database server
|
|
is not installed on the file server that owns
|
|
<Symbol Role="Variable">pathname</Symbol>.</Para>
|
|
<Para>The
|
|
<Function>ttdt_Get_Modified</Function> function
|
|
passes
|
|
<Emphasis>app2run</Emphasis> and
|
|
<Emphasis>ms_timeout</Emphasis> to
|
|
&cdeman.tttk.block.while;, blocking on the reply to the
|
|
<Symbol Role="Message">Get_Modified</Symbol> request it sends.
|
|
</Para>
|
|
</RefSect1>
|
|
<RefSect1>
|
|
<Title>RETURN VALUE</Title>
|
|
<Para>Upon successful completion, the
|
|
<Function>ttdt_Get_Modified</Function> function returns non-zero if the
|
|
<Symbol Role="Message">Get_Modified</Symbol> request receives an affirmative reply within
|
|
<Emphasis>ms_timeout</Emphasis> milliseconds;
|
|
otherwise, it returns zero.
