FLOATOBJ_SubFloat function (winddi.h)

The FLOATOBJ_SubFloat function subtracts the value of type FLOATL from the FLOATOBJ, and returns with the result in the first parameter.

Syntax

VOID FLOATOBJ_SubFloat(
  [in] PFLOATOBJ unnamedParam1,
  [in] FLOATL    unnamedParam2
);

Parameters

[in] unnamedParam1

Pointer to the FLOATOBJ operand. When the function returns, pf will be reset to the value (pf - f).

[in] unnamedParam2

Specifies the FLOATL operand. This value is converted to a FLOATOBJ for the subtraction.

Return value

None

Remarks

The FLOATOBJ_Xxx services allow graphics drivers to emulate floating-point arithmetic. An NT-based operating system does not support kernel-mode floating-point operations on some systems.
