EnumLanguageGroupsProc

An EnumLanguageGroupsProc function is an application defined–callback function. It is called by the EnumSystemLanguageGroups function.

The LANGUAGEGROUP_ENUMPROC type defines a pointer to this callback function. EnumLanguagesGroupsProc is a placeholder for the application defined–function name.

BOOL CALLBACK EnumLanguageGroupsProc(
  LGRPID LanguageGroup,             // language-group identifier
  LPTSTR lpLanguageGroupString,     // language-group identifier string
  LPTSTR lpLanguageGroupNameString, // language-group name string 
  DWORD dwFlags,                    // options
  LONG_PTR  lParam                  // callback parameter
);
