Chapter 12, Problem 12.27HW

Some network programming texts suggest the following approach for reading and writing sockets: Before interacting with the client, open two standard I/O streams on the same open connected socket descriptor, one for reading and one for writing:

FILE *fpin, *fpout;

fpin = fdopen(sockfd, "r");

fpout = fdopen(sockfd, "w”);

When the server finishes interacting with the client, close both streams as follows:

fclose(fpin);

fclose(fpout);

  However, if you try this approach in a concurrent server based on threads, you will create a deadly race condition. Explain.
