iw16 (Windows CE 5.0)
When compiled by the ARM compiler, the iw16 declspec has the same effect as the iwcall declspec; that is, it makes an interworking call.
When compiled by the THUMB compiler, the iw16 declspec has no effect.
Use the iw16 declspec only when you know which compiler, ARM or THUMB, will compile the designated function.
iw16 declspec has no effect on the ARM compiler unless you also use the /QRarch - Specify Target Architecture flag.
Using the /QRinterwork-return - Enable Interworking flag automatically enables the QRarch flag.
