GetCPInfoExW

Retrieves information about any valid installed or available code page.

Syntax

BOOL GetCPInfoExW(
         UINT CodePage,
         DWORD dwFlags,
         LPCPINFOEXW lpCPInfoEx
)  

Parameters

CodePage
Type: UINT 

Identifier for the code page for which to retrieve information. The application can specify the code page identifier for any installed or available code page, or one of the following predefined values. See Code Page Identifiers for a list of identifiers for ANSI and other code pages.

dwFlags
Type: DWORD 

Reserved; must be 0.

lpCPInfoEx
Type: LPCPINFOEXW 

Pointer to a CPINFOEX structure that receives information about the code page.

Return value

Type: BOOL 

Returns a nonzero value if successful, or 0 otherwise. To get extended error information, the application can call GetLastError, which can return one of the following error codes:

• ERROR_INVALID_PARAMETER. Any of the parameter values was invalid.

Remarks

The information retrieved in the CPINFOEX structure is not always useful for all code pages. To determine buffer sizes, for example, the application should call MultiByteToWideChar or WideCharToMultiByte to request an accurate buffer size. If CPINFOEX settings indicate that a lead byte exists, the conversion function does not necessarily handle lead bytes differently, for example, in the case of a missing or illegal trail byte.

Requirements
