_SubSatInt (Windows CE 5.0)
This ARM DSP-enhanced operation performs a saturating subtract instruction. It subtracts the value in Rn from the value in Rm, and places the result in register Rd. This operation affects the sticky-overflow bit 'Q' if overflow occurs in the subtraction.
int _SubSatInt(intArg1,int Arg2);
Parameters
- Arg1
[in] The first term in the difference, the contents of Rm. - Arg2
[in] The second term in the difference, the contents of Rn.
Return Values
The result of the binary arithmetic.
Remarks
The compiler translates this intrinsic into the qsub assembly instruction.
Requirements
