GetFileVersionInfoSizeEx function

Determines whether the operating system can retrieve version information for a specified file. If version information is available, GetFileVersionInfoSizeEx returns the size, in bytes, of that information.

Syntax

DWORD WINAPI GetFileVersionInfoSizeEx(
  _In_  DWORD   dwFlags,
  _In_  LPCTSTR lptstrFilename,
  _Out_ LPDWORD lpdwHandle
);

Parameters

dwFlags [in]

Type: DWORD

Controls which MUI DLLs (if any) from which the version resource is extracted. Zero or more of the following flags.

Value	Meaning
FILE_VER_GET_LOCALISED 0x01	Loads the entire version resource (both strings and binary version information) from the corresponding MUI file, if available.
FILE_VER_GET_NEUTRAL 0x002	Loads the version resource strings from the corresponding MUI file, if available, and loads the binary version information (VS_FIXEDFILEINFO) from the corresponding language-neutral file, if available.

 

lptstrFilename [in]

Type: LPCTSTR

The name of the file of interest. The function uses the search sequence specified by the LoadLibrary function.

lpdwHandle [out]

Type: LPDWORD

When this function returns, contains a pointer to a variable that is set to zero because this function sets it to zero. This parameter exists for historical reasons.

Return value

Type: DWORD

If the function succeeds, the return value is the size, in bytes, of the file's version information.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Call the GetFileVersionInfoSizeEx function before calling the GetFileVersionInfoEx function. The size returned by GetFileVersionInfoSizeEx indicates the buffer size required for the version information returned by GetFileVersionInfoEx.
