Summary

What did we learn?

• Week 36: Basic
  1. Compile functions independently and build up a library; link the main pro- gram to the library.
  2. Static library and Shared library.
  3. Location of standard header files and standard libraries.
  4. Shell commands: ls -l, ps -ax, pipes, redirecting.
  5. Shell script: interactive shell program- ming.
• Week 37-38: File
  1. UNIX system (hierarchy view)
  2. File is generalized in UNIX system. 1

2. Thread creation, termination, join.
3. Synchronize the threads using mutex lock.
4. Example: multi-processes read and write parallel, multi-threads read and write with binary semaphores, creating an array of philosophers,

• Week 44-45: IPC facilities

1. Blocking and non-blocking message pass- ing
2. Basic idea of semaphores(different from the semaphore that used for synchro- nizing threads)
3. overview of shared memory
4. Example: Multi-processes read and write synchronized by semaphores

• Week 46: Pipe
  1. Basic mechanism of the process pipe(uses shell commands)
  2. Basic mechanism of pipe call(build up a pipe with two ends - file descriptors)
  3. Basic feature of named pipe: FIFO(used as a regular file in the UNIX system)
  4. Example: Writer writes onto the FIFO and reader reads from the FIFO
• Week 47: Socket
  1. Socket connection(Socket domain, Socket types)
  2. Example: Socket on local file system(server and client)
