title: Memory allocation - Common memory for a process tree
body: <p>I have to write a code such that, it may create child process via Createprocess API.
  Parent process in the process tree has to allocate the memory common to the total process tree, so that child process can access it. </p>
  
  <p>Malloc, globalalloc does allocate memory within the scope for the process. However I could not extend it for the child process. Was there any APIs in Windows to allocate memory specific for a process tree. If not, Is there any API to allocate memory as a session image.</p>
