What does the following lines of code does ?
boost::interprocess::detail::atomic_cas32( &m_shutdown, 1, 1 ) == 1
According to the documentation, it does the following thing
//! Compare an boost::uint32_t's value with "cmp". //! If they are the same swap the value with "with" //! "mem": pointer to the value //! "with": what to swap it with //! "cmp": the value to compare it to //! Returns the old value of *mem
Can somebody tell me what this atomic_cas32 does ?
