GetSourceLink (hbufSource, lnSource)
Returns the destination of a source link in a Link record. The source buffer is hbufSource and the source line number is lnSource. If the given line does not contain a source link, then an empty string is returned. See also “Link Record”.
The destination link points to a location in some file at some line number. This source link information links two arbitrary locations. For example, the Search Results buffer contains source links for each line that matches the search pattern.
