Property Set Header

Property Set Header

At the beginning of the property set stream is a header. It consists of a byte-order indicator, a format version, the originating operating system version, the class identifier (CLSID), and a reserved field.

The following pseudo-structure illustrates the header.

typedef struct tagPROPERTYSETHEADER 
    // Header 
    WORD   wByteOrder ;  // Always 0xFFFE 
    WORD   wFormat ;     // Always 0 
    DWORD   dwOSVer ;    // System version 
    CLSID  clsID ;       // Application CLSID 
    DWORD  reserved ;    // Should be 1
