/**
|
|
*
|
|
* archive_lookup is used to determine if part of pathname refers to an regular
|
|
* file (archive). If so then its also used to split pathname into archive file
|
|
* and path used to locate file in archive.
|
|
* How it works:
|
|
* We do stat of the parent of input pathname as long as we find an regular file
|
|
* Normally this should never happen. When routine returns true pathname modified
|
|
* and split into archive and inpath. Otherwise nothing happens
|
|
*
|
|
* For example:
|
|
*
|
|
* /music/path/Talco.zip/Talco - Combat Circus/12 - A la pachenka.mp3
|
|
* is split into archive: /music/path/Talco.zip
|
|
* inarchive pathname: Talco - Combat Circus/12 - A la pachenka.mp3
|
|
*
|
|
* Throws on error.
