SM_MAXIMUMTOUCHES top-level constant
int
const SM_MAXIMUMTOUCHES
Nonzero if there are digitizers in the system; otherwise, 0. SM_MAXIMUMTOUCHES returns the aggregate maximum of the maximum number of contacts supported by every digitizer in the system. If the system has only single-touch digitizers, the return value is 1. If the system has multi-touch digitizers, the return value is the number of simultaneous contacts the hardware can provide.
Implementation
const SM_MAXIMUMTOUCHES = 95;
