|
|
* Section:
|
|
* [DllDefaults]
|
|
*
|
|
* Keys:
|
|
* EXTRA_LD_LIBRARY_PATH=/usr/local/lib/wine[:/more/path/to/search[:...]]
|
|
* The path will be appended to any existing LD_LIBRARY_PATH from the
|
|
* environment (see note in code below).
|
|
*
|
|
* DefaultLoadOrder=native,elfdll,so,builtin
|
|
* A comma seperated list of module-types to try to load in that specific
|
|
* order. The DefaultLoadOrder key is used as a fallback when a module is
|
|
* not specified explicitely. If the DefaultLoadOrder key is not found,
|
|
* then the order "dll,elfdll,so,bi" is used
|
|
* The possible module-types are:
|
|
* - native Native windows dll files
|
|
* - elfdll Dlls encapsulated in .so libraries
|
|
* - so Native .so libraries mapped to dlls
|
|
* - builtin Built-in modules
|
|
*
|
|
* Case is not important and only the first letter of each type is enough to
|
|
* identify the type n[ative], e[lfdll], s[o], b[uiltin]. Also whitespace is
|
|
* ignored.
|
|
* E.g.:
|
|
* n,el ,s , b
|
|
* is equal to:
|
|
* native,elfdll,so,builtin
|
|
*
|
|
* Section:
|
|
* [DllOverrides]
|
|
*
|
|
* Keys:
|
|
* There are no explicit keys defined other than module/library names. A comma
|
|
* separated list of modules is followed by an assignment of the load-order
|
|
* for these specific modules. See above for possible types. You should not
|
|
* specify an extension.
|
|
* Examples:
|
|
* kernel32, gdi32, user32 = builtin
|
|
* kernel, gdi, user = builtin
|
|
* comdlg32 = elfdll, native, builtin
|
|
* commdlg = native, builtin
|
|
* version, ver = elfdll, native, builtin
|
|
*
|
|
* Section:
|
|
* [DllPairs]
|
|
*
|
|
* Keys:
|
|
* This is a simple pairing in the form 'name1 = name2'. It is supposed to
|
|
* identify the dlls that cannot live without eachother unless they are
|
|
* loaded in the same format. Examples are common dialogs and controls,
|
|
* shell, kernel, gdi, user, etc...
|
|
* The code will issue a warning if the loadorder of these pairs are different
|
|
* and might cause hard-to-find bugs due to incompatible pairs loaded at
|
|
* run-time. Note that this pairing gives *no* guarantee that the pairs
|
|
* actually get loaded as the same type, nor that the correct versions are
|
|
* loaded (might be implemented later). It merely notes obvious trouble.
|
|
* Examples:
|
|
* kernel = kernel32
|
|
* commdlg = comdlg32
|
