FLOATOBJ structure

The FLOATOBJ structure is used to emulate a floating-point number.

Syntax


typedef struct _FLOATOBJ {
  ULONG ul1;
  ULONG ul2;
} FLOATOBJ, *PFLOATOBJ;

Members

ul1

Reserved for system use.

ul2

Reserved for system use.

Remarks

This structure, in conjunction with the FLOATOBJ_Xxx service routines, allows graphics drivers to emulate floating-point arithmetic in the NT kernel. Floating-point arithmetic is not otherwise supported in the NT kernel code.

Requirements

Header

Winddi.h (include Winddi.h)
