OSVERSIONINFO (Structures)
 
.
Summary
Contains OS version information.

C# Definitions:

// Use this when the unmanaged API expects the structure passed by-value, or
// or if you want to pass it by-reference as a pointer to a structure
struct OSVERSIONINFO {
   public int OSVersionInfoSize;
   [ MarshalAs( UnmanagedType.ByValTStr, SizeConst=128 )]    
   public String versionString;
}

// Use this when you want to pass it by-value even though the unmanaged API
// expects a pointer to a structure.  Being a class adds an extra level of indirection.
