In linux using pthreads
When I call a whatever usual function like for instance:
so I call the same function on different (not shared) data
Can I be sure that the two function calls by the two threads do not share any (internal) data (may be registers or global-library-shared) and so have no side unpredicted effect??
The same question holds for usual functions like sin() exp() pow() rand() nanosleep() etc.
