KSPROPERTY_BOUNDS_LONG union (ks.h)
The KSPROPERTY_BOUNDS_LONG structure defines the bounds for a 32-bit property.
Syntax
typedef union {
struct {
LONG SignedMinimum;
LONG SignedMaximum;
} _SIGNED;
struct {
LONG SignedMinimum;
LONG SignedMaximum;
};
struct {
ULONG UnsignedMinimum;
ULONG UnsignedMaximum;
} _UNSIGNED;
struct {
ULONG UnsignedMinimum;
ULONG UnsignedMaximum;
};
} KSPROPERTY_BOUNDS_LONG, *PKSPROPERTY_BOUNDS_LONG;
Members
_SIGNED
_SIGNED.SignedMinimum
_SIGNED.SignedMaximum
SignedMinimum
Specifies a minimum bound as a signed 32-bit value.
SignedMaximum
Specifies a maximum bound as a signed 32-bit value.
_UNSIGNED
_UNSIGNED.UnsignedMinimum
_UNSIGNED.UnsignedMaximum
UnsignedMinimum
Specifies a minimum bound as an unsigned 32-bit value.
UnsignedMaximum
Specifies a maximum bound as an unsigned 32-bit value.
Remarks
This structure specifies a range of 32-bit values for a property. Use only when the MembersFlags member of the relevant KSPROPERTY_MEMBERSHEADER is set to KSPROPERTY_MEMBER_RANGES. Use this structure in the Members array in the relevant KSPROPERTY_MEMBERSLIST structure.
See the Testcap sample in the Windows Driver Kit (WDK) for examples of usage.
