DosGetLocaleModule is used to facilitate the location and loading of load modules that require a two-character ISO standard language identifier as the first two characters of the dynamic link module name. This function will determine the language identifier if it is not supplied by the user.

If the language of the current or specified locale is not available, DosGetLocaleModule will attempt to find an appropriate substitute such as using the system language.

DosGetLocaleModule can be used to return a pointer to the HMODULE. This pointer can then be used by DosGetResource to load a resource object.
