<H2><A NAME="s5">5. Using the virtual registry</A></H2>
<P>The virtual registry is a general interface to get and set
value from various modules in Linuxconf. You can learn more
about it by reading the "manual" page for the vregistry
module.
<P>We describe here how to use it from a shellmod script.
<P>
<H2><A NAME="ss5.1">5.1 vreg_set registry_variable_name value</A>
</H2>
<P>You can set any variable by issuing the vreg_set command.
The variable name is one registry variable. You can learn the
about the available variable by running <CODE>/sbin/vregistry --list</CODE>.
<P>You generally issue several vreg_set statements and then you
call the vreg_do function to commit the request. The various
modules are updated at this time only.
<P>
<P>
<H2><A NAME="ss5.2">5.2 vreg_get registry_variable_name shell-variable</A>
</H2>
<P>This will collect the value of the registry variable into
a local variable of the shell named shell-variable.
<P>You generally issue several vreg_get statements and then you
call the vreg_do function to commit the request. After having
called vreg_do, your shell variables are properly assigned.
<P>
<BLOCKQUOTE><CODE>
<PRE>
qecho vreg_get samba.workgroup workgroup
qecho vreg_get samba.winsserver wins
# At this point, neither workgroup or wins are assigned
vreg_do
qecho notice "Your workgroup is $workgroup, wins server, $wins"
</PRE>
</CODE></BLOCKQUOTE>
<P>
<H2><A NAME="ss5.3">5.3 vreg_do</A>
</H2>
<P>vreg_do is a shell function. so you use it directly unlike most
other shellmod command which are "echoed". vreg_do acts like
the dispatch command. It requests action and grab the results.
