Retrieves information about a locale specified by identifier.
int GetLocaleInfoA( LCID Locale, LCTYPE LCType, LPSTR lpLCData, int cchData );
The locale information to retrieve. For detailed definitions, see the LCType parameter of GetLocaleInfoEx.
Pointer to a buffer in which this function retrieves the requested locale information. This pointer is not used if cchData is set to 0. For more information, see the Remarks section.
Size, in TCHAR values, of the data buffer indicated by lpLCData. Alternatively, the application can set this parameter to 0. In this case, the function does not use the lpLCData parameter and returns the required buffer size, including the terminating null character.
Returns the number of characters retrieved in the locale data buffer if successful and cchData is a nonzero value. If the function succeeds, cchData is nonzero, and LOCALE_RETURN_NUMBER is specified, the return value is the size of the integer retrieved in the data buffer; that is, 2 for the Unicode version of the function or 4 for the ANSI version. If the function succeeds and the value of cchData is 0, the return value is the required size, in characters including a null character, for the locale data buffer.
The function returns 0 if it does not succeed. To get extended error information, the application can call GetLastError, which can return one of the following error codes:
- ERROR_INSUFFICIENT_BUFFER. A supplied buffer size was not large enough, or it was incorrectly set to NULL.
- ERROR_INVALID_FLAGS. The values supplied for flags were not valid.
- ERROR_INVALID_PARAMETER. Any of the parameter values was invalid.
For the operation of this function, see Remarks for GetLocaleInfoEx.
int ret; CALID calid; DWORD value;
When the ANSI version of this function is used with a Unicode-only locale identifier, the function can succeed because the operating system uses the system code page. However, characters that are undefined in the system code page appear in the string as a question mark (?).
