Function:
GetVersionExA
GetVersionEx
The GetVersionEx function obtains extended information about the
version of the operating system that is currently running.
Parameters
lpVersionInfo
[in/out] 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 a nonzero value.
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.
