FLOATOBJ_MulLong function (winddi.h)

The FLOATOBJ_MulLong function multiplies the FLOATOBJ by the value of type LONG, and returns with the result in the first parameter.

Syntax

VOID FLOATOBJ_MulLong(
  [in, out] PFLOATOBJ unnamedParam1,
  [in]      LONG      unnamedParam2
);

Parameters

[in, out] unnamedParam1

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

[in] unnamedParam2

Specifies the LONG operand. This value is converted to a FLOATOBJ for the multiplication.

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.
