#include "l_bitmap.h"

L_LTKRN_API L_CHAR * L_Setlocale(category, locale)

Sets the locale for the library.


L_INT category

Category affected by the locale.

const L_CHAR * locale

Locale name.  Pass NULL to return the current locale.


Value Meaning
!NULL A pointer to the string representing the specified locale and category
NULL Indicates that the category or locale parameter value was invalid


This function is used under rare circumstances. It is necessary only when running non-UNICODE applications that must deal with text (for example, filename strings) that is not part of the ASCII character set (for example, Japanese characters). Non-ASCII text (i.e. a Japanese or Arabic character) can be stored non-ambiguously in UNICODE. However, for non-UNICODE applications, the multi-byte representation of such characters depends on the code page. In this case, you must set the code page appropriately. For example, a non-UNICODE application can display Japanese characters only if the code page is set to a Japanese code page (like Japanese_Japan.932).

Pass NULL for the parameter locale to get the current locale, leaving the current locale unchanged.

Internally, this function calls the Microsoft C runtime function, setlocale. For details, see the MSDN documentation.

Required DLLs and Libraries

#include <locale.h> 
L_CHAR* DisplayCurrentLocale() 
   // Display the current locale 
   L_CHAR *pszMsg = L_Setlocale(LC_ALL, NULL); 
   if (pszMsg != NULL) 
      MessageBoxA(NULL, pszMsg, "Current Locale", MB_OK); 
   return pszMsg; 
L_INT SetlocaleExample()  
   L_CHAR *pszOriginalLocale = DisplayCurrentLocale(); 
   // Set the locale for English/United states 
   L_Setlocale(LC_ALL, "English"); 
   // Set the locale for Japanese 
   L_Setlocale(LC_ALL, "Japanese"); 
   // Set the locale for arabic 
   L_Setlocale(LC_ALL, "Arabic"); 
   // Set to the original locale 
   L_Setlocale(LC_ALL, pszOriginalLocale);
