FLOATOBJ_SubLong function (winddi.h)
The FLOATOBJ_SubLong function subtracts the value of type LONG from the FLOATOBJ, and returns with the result in the first parameter.
void FLOATOBJ_SubLong( [in, out] PFLOATOBJ unnamedParam1, [in] LONG unnamedParam2 );
[in, out] unnamedParam1
Pointer to the FLOATOBJ operand. When the function returns, pf will be reset to the value (pf - l).
Specifies the LONG operand. This value is converted to a FLOATOBJ for the subtraction.
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.
