    POSIXThreads
           ThePOSIXthreadsAPIaddsthreadingtoUnix.
           Youwill also see this API called Pthreads or pthreads.
           Early Unix provided only the process model for concurrency.
           POSIXthreads look like processes, but share more resources.
           Every POSIX thread starts with a function.

    POSIXSynchronization
           Pthreads also provides synchronization mechanisms.
           In fact, it provides a rather rich set of options!

           Only semaphores are covered in detail in CS:APP.

    Compilation with Pthreads
           Pthreads may require extra compilation options.
           OnmodernLinux,use-pthreadbothwhencompilingandlinking.
           Onsomeothersystems,otheroptions may be required:
                     Provide a different compiler or linker option (such as
                     -pthreads)
                     Compile with some preprocessor define (e.g., -DPTHREAD,
                     -D_REENTRANT)
                     Link with a library (e.g., -lpthread)
