The DDMORESURFACECAPSstructure contains the driver surface capabilities required by the addition of new capability information to the application's DDCAPSstructure in DirectX 6.0. These driver capabilities are an addition to those described in DDCORECAPS.
typedef struct _DDMORESURFACECAPS { DWORD
dwSize
;
DDSCAPSEX
ddsCapsMore
;
struct
tagExtendedHeapRestrictions
{
DDSCAPSEX
ddsCapsEx
;
DDSCAPSEX
ddsCapsAlt
;
} ddsExtendedHeapRestrictions[1];
} DDMORESURFACECAPS, FAR * LPDDMORESURFACECAPS;
Members
- dwSize
- Size of the structure. This member must be initialized before the structure is used.
- ddsCapsMore
- DDSCAPSEXstructure containing new surface capabilities that the driver can create in display memory. These capabilities are in addition to the capabilities provided by the DDCORECAPSstructure.
- tagExtendedHeapRestrictions
- Structure that contains the display memory heap restrictions. Zero or more of these structures are returned by the driver depending on the number of heaps indicated in the DDHALINFOstructure. Each of the tagExtendedHeapRestrictionsstructures contains the following members:
- ddsCapsEx
- DDSCAPSEXstructure that contains the capabilities to be excluded from the memory heap. This member is equivolent to the ddsCapsmember of the VIDMEMstructure.
- ddsCapsAlt
-
DDSCAPSEXstructure that
indicates what this memory cannot be used for if no other memory is
found on the first pass. This member is equivalent to the
ddsCapsAltmember of the
VIDMEMstructure.
