I am interested in the contents of the intermediate files xref and fileidx (I have been studing the stable release of lxr, I guess that the development version uses the same files) used by lxr for fast symbol access.

This is the first time I read a program written in Perl, so I cannot determine clearly the contets of those files (xref and fileidx) only by looking at the code. I have found that the xref file is written using the DB_HASH format provided by DB_File class, but I cannot guess the data types of the pairs (key, value).

Where can I found this information? Perl data types will be enough for this.

Thanks and regards,
