View source for WinQueryVersion

This function is included for compatibility purposes only, and its use is not recommended. It is recommended that [[DosQuerySysInfo]] (see the Control Program Programming Reference) be used to return the version, the revision level, and the environment of PM. 

==Syntax==
 WinQueryVersion(hab)

==Parameters==
;hab ([[HAB]]) - Input
: Anchor-block handle.

==Returns==
;fSysInf ([[ULONG]]) - returns
: System information within which the application is operating.
: This information consists of 4 bytes packed into the ULONG variable as follows:
:; Byte 0 (bits 0-7): Major version.
:; Byte 1 (bits 8-15): Minor version.
:; Byte 2 (bits 16-23): Revision number.
:; Byte 3 (bits 24-31): Reserved.

==Example Code==
<pre>
#define INCL_WINWINDOWMGR /* Or use INCL_WIN, INCL_PM, Also in COMMON section */
#include <os2.h>

HAB      hab;      /*  Anchor-block handle. */
ULONG    fSysInf;  /*  System information within which the application is operating. */

fSysInf = WinQueryVersion(hab);
</pre>

This example gets the version of PM that is running.
<pre>
#define INCL_WINWINDOWMGR
#include <OS2.H>
#include <stdio.h>

HAB  hab;
ULONG lVer;

lVer = WinQueryVersion(hab);
printf("PM revision is %d ", lVer);
</pre>
