DEFINE_DEVPROPKEY

  • Article

In Windows Vista and later versions of Windows, the DEFINE_DEVPROPKEY macro creates a DEVPROPKEY structure that represents a device property key in the unified device property model.

#ifdef INITGUID
#define DEFINE_DEVPROPKEY(name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8, pid) EXTERN_C const DEVPROPKEY DECLSPEC_SELECTANY name = { { l, w1, w2, { b1, b2,  b3,  b4,  b5,  b6,  b7,  b8 } }, pid }
#else
#define DEFINE_DEVPROPKEY(name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8, pid) EXTERN_C const DEVPROPKEY name
#endif // INITGUID

Members

name
The name of a DEVPROPKEY structure that represents a device property key.

l
An unsigned long-typed variable that supplies the value of the data1 member of the fmtid member of the DEVPROPKEY structure.

w1
An unsigned short-type variable that supplies the value of the data2 member of the fmtid member of the DEVPROPKEY structure.

w2
An unsigned short-type variable that supplies the value of the data3 member of the fmtid member of the DEVPROPKEY structure.

b1
A byte-typed variable that supplies the value of the data4[0] member of the fmtid member of the DEVPROPKEY structure.

b2
A byte-typed variable that supplies the value of the data4[1] member of the fmtid member of the DEVPROPKEY structure.

b3
A byte-typed variable that supplies the value of the data4[2] member of the fmtid member of the DEVPROPKEY structure.

b4
A byte-typed variable that supplies the value of the data4[3] member of the fmtid member of the DEVPROPKEY structure.

b5
A byte-typed variable that supplies the value of the data4[4] member of the fmtid member of the DEVPROPKEY structure.

b6
A byte-typed variable that supplies the value of the data4[5] member of the fmtid member of the DEVPROPKEY structure.

b7
A byte-typed variable that supplies the value of the data4[6] member of the fmtid member of the DEVPROPKEY structure.

b8
A byte-typed variable that supplies the value of the data4[7] member of the fmtid member of the DEVPROPKEY structure.

pid
A DEVPROPID-typed variable that supplies the value of the pid (property identifier) member of the DEVPROPKEY structure. The property identifier must be greater than or equal to two.
