ObjectInfo

struct ObjectInfo {
    ULONG OI_LinearAddress;  // starting address of object
    ULONG OI_Size;           // size of object (in bytes)
    ULONG OI_ObjType;        // see below
    ULONG OI_Resident;       // see below
};
 

Contains information about a memory object in a VxD.

OI_ObjType

Object type, which can be one of the following values.

Constant	Value	Meaning
RCODE_OBJ	-1	Real-mode stub (ignored for dynamically loadable VxDs)
LCODE_OBJ	0x01	Locked code segment
LDATA_OBJ	0x02	Locked data segment
PCODE_OBJ	0x03	Pageable code segment
PDATA_OBJ	0x04	Pageable data segment
SCODE_OBJ	0x05	Static code segment (dynamically loadable VxDs only)
SDATA_OBJ	0x06	Static data segment (dynamically loadable VxDs only)
CODE16_OBJ	0x07	16-bit V86 segment
ICODE_OBJ	0x11	Initialization-time only code segment
IDATA_OBJ	0x12	Initialization-time only data segment
ICODE16_OBJ	0x13	Initialization-time only 16-bit V86 segment

OI_Resident

Whether or not the memory object is static. This value is zero for VxDs that are not dynamically loadable.

The DeviceInfo structure includes the address of an array of ObjectInfo structures that describe a VxDs memory objects.
