iw32 (Windows Embedded CE 6.0)
1/5/2010
When compiled by the THUMB compiler, the iw32 declspec has the same effect as the iwcall declspec; that is, it makes an interworking call.
When compiled by the ARM compiler, the iw32 declspec has no effect.
Use the iw32 declspec only when you know which compiler, ARM or THUMB, will compile the designated function.
