The example shows how you can use link and xref tags to create hyperlinks to topics and assign text to links that is different from the topic ID to which the link is created. In this example the link text is another function and the topic ID is Bar.
// Foo does nothing meaningful, it just
// calls <link Bar, another function> and
// that's all.
-----------
// Foo does nothing meaningful, it just
// calls <xref target= "Bar" text= "another function"/> and
// that's all.
void Foo();
// Bar is called by Foo and returns a
// checksum for the argument s.
int Bar(char *s);
