The GetVersionEx function obtains extended information about the version of the operating system that is currently running.

BOOL GetVersionEx(

LPOSVERSIONINFO lpVersionInformation	// pointer to version information structure
);

Parameters
lpVersionInformation

Pointer to an OSVERSIONINFO data structure that the function fills with operating system version information.

Before calling the GetVersionEx function, set the dwOSVersionInfoSize member of the OSVERSIONINFO data structure to sizeof(OSVERSIONINFO).

Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError. The function fails if you specify an invalid value for the dwOSVersionInfoSize member of the OSVERSIONINFO structure.

Remarks
The GetVersionEx function supersedes the GetVersion function and is the preferred method for obtaining operating system version number information. New applications should use the GetVersionEx function rather than the GetVersion function.
