In C++, you might write #include <atomic> std::atomic<int> counter; then you can just do ++counter; --counter; as usual, while in C you’d have to write #include <stdatomic.h> atomic_int counter; atomic_fetch_add(&counter, 1); atomic_fetch_sub(&counter, 1); See http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf for the C11 spec (section 7.17 is the part you’re interested in), or http://en.cppreference.com/w/cpp/atomic for C++11 documentation (you could look in the spec also, but personally I find the C++ specification hard to read).
