<P >vgSrcAssoc(source, association);<p></p></P>
<P >‘vg’ is our product code<p></p></P>
<P >‘Src’ is the placeholder of the source instance<p></p></P>
<P >‘Assoc’ is the placeholder of the Association to be made<p></p></P>
<P >Example<p></p></P>
<P >/*declare variables*/<p></p></P>
<P >vgChannel *channel;<p></p></P>
<P >vgWindow *window;<p></p></P>

<P >vgAddSrcAssoc(source, association);<p></p></P>
<P >    ‘vg’ (I think you’ve got it now)<p></p></P>
<P >    ‘Add’ is the action adding another association to our source<p></p></P>
<P >    ‘Src’ is the placeholder of the source instance<p></p></P>
<P >    ‘Assoc’ is the placeholder of the Association to be added<p></p></P>

<P >vgRemSrcAssoc(source, association);<p></p></P>
<P >    ‘Rem’ is the action: removing an association from our source<p></p></P>
<P >    ‘Src’ is the placeholder of the source instance<p></p></P>
<P >    ‘Assoc’ is the placeholder of the Association to be removed<p></p></P>

<P >vgGetSrcAssoc(source, index);<p></p></P>
<P >    ‘Get’ is the action: getting the handle of an association to our source.<p></p></P>
<P >    ‘Src’ is the placeholder of the source instance<p></p></P>
<P >    ‘Assoc’ is the placeholder of the Association we are getting<p></p></P>
<P >Example<p></p></P>
