GetLocaleInfo

The GetLocaleInfo function retrieves information about a locale.

int GetLocaleInfo(

LCID Locale,	// locale identifier
LCTYPE LCType,	// type of information
LPTSTR lpLCData,	// address of buffer for information
int cchData	// size of buffer
);

Parameters

Locale

Specifies the locale to retrieve information for. This parameter can be a locale identifier created by the MAKELCID macro, or one of the following predefined values:

LOCALE_SYSTEM_DEFAULT	Default system locale.
LOCALE_USER_DEFAULT	Default user locale.

LCType

Specifies one of the LCTYPE constants to indicate the type of information to be retrieved.

All LCTYPE values are mutually exclusive, with the exception of LOCALE_NOUSEROVERRIDE. An application may use the binary-OR operator to combine LOCALE_NOUSEROVERRIDE with any other LCTYPE value. If passed such an LCType value, the function bypasses user overrides, and returns the system default value for the requested LCID.

lpLCData

Points to a buffer to receive the requested data.

cchData

Specifies the size, in bytes (ANSI version) or characters (Unicode version), of the lpLCData buffer. If cchData is zero, the function returns the number of bytes or characters required to hold the information, and the buffer pointed to by lpLCData is not used.

Return Values

If the function succeeds, the return value is the number of bytes (ANSI version) or characters (Unicode version) written to the destination buffer, or if the cchData parameter is zero, the number of bytes or characters required to hold the locale information.

If the function fails, the return value is zero. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:

ERROR_INSUFFICIENT_BUFFER

ERROR_INVALID_FLAGS

ERROR_INVALID_PARAMETER

Remarks

The GetLocaleInfo function always retrieves information in text format. If the information is a numeric value, the function converts the number to text using decimal notation.
