## File search

- Overview
- Placeholders
- Search order for dkapp_find_file()
- Search order for dkapp_find_cfg()

### Overview

The dkapp module provides the functions dkapp_find_file() to search for data or resource files and dkapp_find_cfg() to search for configuration files.
Both functions search for a file in a number of directories to allow user-specific, language-specific and/or compressed versions.

### Placeholders

The following placeholders are used in the directory lists below:

- cwd: current working directory
- home: the users home directory
- prefix: installation prefix (``/usr/local'')
- appname: application name
- groupname: application group name
- appdir: application directory
- shareddir: directory shared between applications
- windir: the Windows directory (on Windows systems only)
- sysconfdir: system configuration directory (/etc or the Windows directory)
- language: the users preferred language
- region: the users preferred region
- encoding: the users preferred encoding

### Search order for dkapp_find_file()

The dkapp_find_file() functions searches for

- filename,
- filename.gz (when compiled with gzip support) and
- filename.bz2 (when compiled with bzip2 support)

in the following directories:

- cwd
- home
- home/.defaults
- appdir/language/region/encoding
