Perform the operation op on file descriptor fd.

The values used for op are operating system dependent, and are available as

constants in the fcntl or termios library modules, using the same names as

|

The argument `arg` is optional, and defaults to 0; it may be an int or a
|
|
buffer containing character data (most likely a string or an array).
|
|
|
|
If the argument is a mutable buffer (such as an array) and if the
|
|
mutate_flag argument (which is only allowed in this case) is true then the
|
|
buffer is (in effect) passed to the operating system and changes made by
|
|
the OS will be reflected in the contents of the buffer after the call has
|
|
returned. The return value is the integer returned by the ioctl system
|
|
call.
|
|
|
|
If the argument is a mutable buffer and the mutable_flag argument is not
|
|
passed or is false, the behavior is as if a string had been passed. This
|
|
behavior will change in future releases of Python.
|
|
|
|
If the argument is an immutable buffer (most likely a string) then a copy
|
|
of the buffer is passed to the operating system and the return value is a
|
|
string of the same length containing whatever the operating system put in
|
|
the buffer. The length of the arg buffer in this case is not allowed to
|
|
exceed 1024 bytes.
|
|
|
|
If the arg given is an integer or if none is specified, the result value is
|
|
an integer corresponding to the return value of the ioctl call in the C
|
|
code.

A wrapper around the fcntl() locking calls.

fd is the file descriptor of the file to lock or unlock, and operation is one
|
|
of the following values:
|
|
|
|
LOCK_UN - unlock
|
|
LOCK_SH - acquire a shared lock
|
|
LOCK_EX - acquire an exclusive lock
|
|
|
|
When operation is LOCK_SH or LOCK_EX, it can also be bitwise ORed with
|
|
LOCK_NB to avoid blocking on lock acquisition. If LOCK_NB is used and the
|
|
lock cannot be acquired, an IOError will be raised and the exception will
|
|
have an errno attribute set to EACCES or EAGAIN (depending on the operating
|
|
system -- for portability, check for either value).
|
|
|
|
length is the number of bytes to lock, with the default meaning to lock to
|
|
EOF. start is the byte offset, relative to whence, to that the lock
|
|
starts. whence is as with fileobj.seek(), specifically:
|
|
|
|
0 - relative to the start of the file (SEEK_SET)
|
|
1 - relative to the current buffer position (SEEK_CUR)
|
|
2 - relative to the end of the file (SEEK_END)
