title: Global data being written by one thread and read by multiple threads
body: <p>There is one thread and only one thread which will be writing/modifying a data structure. The data structure has one field which is a socket descriptor opened by the writing thread. Two other threads will be reading the data structure and will have to do something (like polling the socket(s) stored in the structure for input data).</p>
  
  <p>One thread will read one global structure written by the writing thread while the other thread will read a second global structure. In essence, the two reading threads are not accessing the same global structure. </p>
  
  <p>My question is, if the writing thread makes changes to the data structure which maybe adding more records in the data structure or deleting them, will the process crash? Is there any room for any kind of instance where a run-time crash can occur?</p>
  
  <p>P.S. I'm using POSIX Threads working on a Linux environment</p>
