|

*
|
|
* DefaultLoadOrder=native,elfdll,so,builtin
|
|
* A comma separated 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 explicitly. 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

|
* specify an extension.

* Examples:
|
|
* kernel32, gdi32, user32 = builtin
|
|
* kernel, gdi, user = builtin
|
|
* comdlg32 = elfdll, native, builtin
|
