The GDI Base Object, which is a header at the top of every GDI Object. The structure is called BASEOBJECT and is defined as follows for Windows XP, Windows 2003 and Vista, same for 64 Bit Versions:
typedef struct _BASEOBJECT
{
/* 00 */ HANDLE hHmgr;
/* 04 */ ULONG ulShareCount;
/* 08 */ USHORT cExclusiveLock;
/* 0a */ USHORT BaseFlags;
/* 0c */ PW32THREAD Tid;
} BASEOBJECT, *POBJ;
typedef struct _BASEOBJECT DD_BASEOBJECT, *PDD_BASEOBJECT; //(correct?)
The pointer to a _BASEOBJECT is known as a POBJ.
BaseFlags
- 0x800 for objects that are allocated from a lookaside list (DC, region, bitmap, palette, font and brush)
