title: convert pointer value to string and back again
body: <p>if I have a pointer to int , and it's value is <code>0x0012FF7C</code> how can I store this value in a string , and then make the reverse ( I mean convert the value stored in string to <code>int*</code>)</p>
  
  <p>I need this way because I need to send a memory location between two process in PVM, so I need to send the value of a pointer as a string, and receive this string in the second process and store it's value in a pointer</p>
