socket.makefile

socket.makefile(mode='r')

  • This function creates and returns a file object f
  • This file object f reads from and/or writes to the socket
  • Typically, this refers to the server socket
  • This can be used for logging

Example of makefile

>>> import socket
>>> sock = socket(AF_INET, SOCK_STREAM)
>>> serv_addr = ('', 25000)  # server socket binds...
>>> sock.bind(serv_address)  # ...to port 25000
>>> sock.listen(5)  # only allow 5 client connections

>>> # Make file for server socket
>>> server, client_addr = sock.accept()
>>> sf = server.makefile("r+b", bufsize=0)

>>> # Make file for client socket
>>> client = socket.create_connection(serv_addr)
>>> cf = client.makefile('r_b', bufsize=0)

>>> sf.write('hello world')
>>> sf.flush()
>>> sf.close()
>>> server.close()
>>> print(cf.read(99))  # does not hang
