_thread库方法

(1) _thread.error

(2)_thread.LockTyoe

(3)_thread.start_new_thread

(4)_thread.interrupt_main

Raise a KeyboardInterrupt exception in the main thread. A subthread can use this function to interrupt the main thread.

(5)_thread.exit

(6)_thread.allocate_lock

import _thread

a_lock=_thread.allocate_lock()

with a_lock:

print("a_lock is locked while this executes")

(7)_thread.get_ident

(8)_thread.stack_size

(9)_thread.TIMEOUT_MAX

(10)lock.acquire(waitflag=1,timeout=-1)

Without any optional argument, this method acquires the lock unconditionally, if necessary waiting until it is released by another thread (only one thread at a time can acquire a lock — that’s their reason for existence).

If the integer waitflag argument is present, the action depends on its value: if it is zero, the lock is only acquired if it can be acquired immediately without waiting, while if it is nonzero, the lock is acquired unconditionally as above.

If the floating-point timeout argument is present and positive, it specifies the maximum wait time in seconds before returning. A negative timeout argument specifies an unbounded wait. You cannot specify a timeout if waitflag is zero.

The return value is True if the lock is acquired successfully, False if not.

(11)lock.release()

(12)lock.locked()
