C++ thread bind core

Webboost::bind is a generalization of the standard functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions. Author(s) Peter Dimov First Release 1.25.0 WebWindows is using SetThreadAffinityMask (handle [i], 1 << i); Function to bind the thread to the CPU core, the first parameter handle [i] is the handle of the thread, and the second parameter represents the number of the CPU core. SetThreadAffinityMask () returns a non-zero value to indicate success in binding the CPU core, and a zero value ...
