A long time ago, when everyone wrote single-threaded programs, one of the most effective ways to make a program run faster was to sit back and do nothing. Optimizations in the next generation of hardware and the next generation of compilers would make the program run exactly as before, just...

In addition to client-server applications, where the client can be a multithreaded program, a typical use of multithreaded applications is in three-tier (also called client-agent-server) architectures. In this architecture the client is concerned only with presentation services. The agent (or applic...

He says, “We've used it like optionals but we've got the power of errors we know what went wrong and we can pull that error out at any time that we need it. The idea was we have one return type whether we succeeded or failed. We get a record of our first error and we are...
That means you must convert it to a more specific type before you can program against it. In the previous example, the sender parameter must be converted to a TextBox in order to access its Text property. If you have experience building form-based applications with earlier versio...
A pointer to a parameter to be passed to the routine at which the new thread starts. Like most Pthreads functions,pthread_createreturns a value that indicates whether it has succeeded or failed. A zero value represents success, and a nonzero value indicates and identifies an error. ...
This example illustrates a simple loop, with the application reading data from the communications device, then writing the input back to the same device, echoing all input back over the communications line. The program reads up to 1024 bytes at a time, and then writes the number of bytes ju...

No memory leaks. This is the obvious advantage. Both garbage collection schemes promise to dispose of all objects at some point during program execution, but neither can guarantee when, except that no object shall be removed until at least all program references to it are removed. It rewards ...
