\page pi_localization Localization

If a module requires localized resources, it can register the
localized resource libraries with the module manager when it receives
the init_module() callback.  Note that you can only register localized
resource libraries during init_module().

The localized resource library is global to a module.  Each plug-in is
not allowed to define its own localization library, although it is
free to load and use any library as it sees fit.  The module manager
does not manage these libraries for the plug-in.

\section pi_loc_spec Specification of localized resources

In order to register localized resource libraries, a module calls
kmm_set_locale_info().  The \a locales parameter to the function holds
a pointer to an array of ::kmm_module_locale records.  Each record
specifies one language code and a filename of a library that holds the
language resources for that language.

It is recommended that you use the LOCALE_DEF convenience macro when
defining locale records for use with kmm_set_locale_info().  This will
ensure that future changes in the API will only minimally affect your
code.  For example:

\code
kmm_module_locale my_locales[] = {
LOCALE_DEF(MAKELANGID(LANG_ENGLISH,SUBLANG_ENGLISH_US), L"english.dll", KMM_MLOC_FLAG_DEFAULT),
LOCALE_DEF(MAKELANGID(LANG_DUTCH,SUBLANG_DUTCH), L"dutch.dll", 0),
LOCALE_DEF(MAKELANGID(LANG_SPANISH,SUBLANG_SPANISH_MODERN), L"spanish.dll", 0)
};

int n_locales = sizeof(my_locales)/sizeof(my_locales[0]);

...

kmm_set_locale_info(h_module, my_locales, n_locales);

...
\endcode

See kmm_set_locale_info() and ::kmm_module_locale for more info.

\section pi_loc_how Selection of localized resource library

The module manager searches the array of ::kmm_module_locale objects
passed into the kmm_set_locale_info() function for one that matches
the current user locale (as opposed to the current system locale).  A
record matches the locale if it has the same language ID.  

If a match is found, that library is selected.  Otherwise, the list is
searched for one that is compatible with the current user locale.  A
locale record is compatible with the user locale if the primary
language matches.

If a match is still not found, the first record in the locale array
that has the ::KMM_MLOC_FLAG_DEFAULT flag set will be selected.

If a match is still not found, then the kmm_set_locale_info() will
return ::KHM_ERROR_NOT_FOUND.

\section pi_loc_usage Using localization

The following convenience macros are available for using a module
handle to load resources from the corresponding resource library.
However, for performance reasons, it is advisable to obtain a handle
to the resource library loaded by the module manager using
kmm_get_resource_module() and then use it to access resources using
the regular WIN32 API.

- ::kmm_LoadBitmap
- ::kmm_LoadCursor
- ::kmm_LoadIcon
- ::kmm_LoadImage
- ::kmm_LoadMenu
- ::kmm_LoadString
