Set the value of the given socket option. The needed symbolic constants are defined in the
socket module (
SO_*
etc.). The value can be an integer or a bytes-like object representing
a buffer.
socket.settimeout(value)
Set a timeout on blocking socket operations. The value argument can be a nonnegative
floating point number expressing seconds, or
None
. If a non-zero value is given,
subsequent socket operations will raise a timeout exception if the timeout period value has
elapsed before the operation has completed. If zero is given, the socket is put in non-
blocking mode. If None is given, the socket is put in blocking mode.
socket.setblocking(flag)
Set blocking or non-blocking mode of the socket: if flag is false, the socket is set to non-
blocking, else to blocking mode.
This method is a shorthand for certain
settimeout()
calls:
sock.setblocking( True ) is equivalent to sock.settimeout( None )
sock.setblocking( False ) is equivalent to sock.settimeout( 0.0 )
socket.makefile(mode='rb')
Return a file object associated with the socket. The exact returned type depends on the
arguments given to makefile(). The support is limited to binary modes only (
rb
and
wb
).
CPython’s arguments:
encoding
,
errors
, and
newline
are not supported.
The socket must be in blocking mode; it can have a timeout, but the file object’s internal
buffer may end up in a inconsistent state if a timeout occurs.
Difference to CPython
Closing the file object returned by
makefile()
WILL close the original socket as well.
socket.read(size)
Read up to size bytes from the socket. Return a bytes object. If
size
is not given, it
behaves just like socket.readall(), see below.
socket.readall()
Read all data available from the socket until EOF. This function will not return until the socket
is closed.
