以微秒为单位获取当前时间戳 [英] getting current timestamp in micro secs
问题描述
我想以微秒精度找到当前时间戳。
要求是,
我的函数在无限循环中执行。
我测量一个值并检查计算出的值是否符合我的预期
9忘记所有这些东西。
我想在每次事件发生时打印时间戳。
所以我的要求是打印当前的时间戳。
so我可以计算出事件发生后的平均时间(以微秒为单位)......
我希望我能明白我的要求。 />
任何人都可以帮我解决这个问题。
我搜索了很多讨论但是找不到满意的答案。
提前感谢
Hi,
I want to find the current time stamp in micro sec precision.
The requirement is,
my function is executed in an infinite loop.
I measure a value and check if the value computed is what i expected
9forget all this stuff).
I want to print the time stamp every time that event occurs.
So my requirement is printing the current timestamps.
so I can calculate the average time (in micro secs) after which such
an event occur...
I hope I made my requirement clear.
Can anybody pls help me with this problem.
I searched many discussion but couldn''t find satisfactory answer.
thanks in advance

没有这样做的便携方式,所以你必须使用一些
系统特定的方法来做它。
如果你使用的是类Unix系统,那么你将可能有
gettimeofday()可用。但请注意,即使它确实返回一个值(微秒),它会打开,大多数系统,不准确超过10毫秒
左右。
如果你真的需要微秒级的精度,那么无论你找到什么方法,你的特定系统都是非常具体的,而且根本不需要.b $ b便携式。
