title: How do I check if a process is running from c++ code?
body: <p>I'm writing a C++ app that will communicate with another process via boost::interprocess, however I need to check if the other process is actually running first - as the other process is responsible for creating the inter-process shared memory. How do I check if the other process is running ?</p>
  
  <p>folks, I'm specifically required to check other processes</p>
