2016年7月10日 · wait(): when synchronized multiple threads access same Object one by one. sleep(): when synchronized multiple threads wait for sleep over of sleeping thread. Hold lock: wait(): release the lock for other objects to have chance to execute. sleep(): keep lock for at least t times if timeout specified or somebody interrupt. Wake-up condition:

2017年2月26日 · I'm confused about the exact meaning of the wait statement. What happens in this case: forever begin wait (vif.xn_valid == 1'b1); @(posedge vif.clk); end Is the wait statement blocking? Is the @(posedge vif.clk) executed every time inside the loop, regardless of the evaluation of the wait expression? And in this case:

If you want a no busy wait for Lua for use in frames for videogames or applications, perhaps wxLua or other libraries may provide less resource craving sleep functions. The sleep function I provide is useful for bugtesting, automation in smaller scripts and less serious projects.

2013年1月10日 · Using wait.for, you can call any standard nodejs async function, as if it were a sync function, without blocking node's event loop. You can code sequentially when you need it, which is, (I'm guessing) perfect to simplify your scripts for …

console.log('before'); wait(7000); //7 seconds in milliseconds console.log('after'); I've arrived here because I was building a simple test case for sequencing a mix of asynchronous operations around long-running blocking operations (i.e. expensive DOM manipulation) and this is my simulated blocking operation.

2016年10月13日 · Quoting wait/waitpid, The waitpid() function is provided for three reasons: To support job control. To permit a non-blocking version of the wait() function. To permit a library routine, such as system() or pclose(), to wait for its children without interfering with other terminated children for which the process has not waited. and

Private Sub Wait(ByVal Seconds As Double, Optional ByRef BreakCondition As Boolean = False) Dim l_WaitUntil As Date l_WaitUntil = Now.AddSeconds(Seconds) Do Until Now > l_WaitUntil If BreakCondition Then Exit Do DoEvents() Loop End Sub

Never wait for timeout in production. Tests that wait for time are inherently flaky. Use Locator actions and web assertions that wait automatically. Caveats to the above: sleeping can be useful for temporary debugging while developing a script, and for throttling requests to avoid overwhelming a server.
