C++中err是什么意思

Question

如题所述

Answer 1

我也觉得是不是cerr
或者是c语言

cerr是标准错误输出，是没有缓冲的，发送给它的内容立即被输出。

预先定义的ostream类对象用来完成标准设备的输出，包括4个；
1，cout，标准输出
2，cerr，
3，cin，
4，clog，类似cerr，但有缓冲，缓冲满是被输出

Answer 2

err
An error output stream for the service. Data written to the stream is automatically redirected to the event log as error events using the event source specified to jntsvc. Each line printed to the stream results in a new event. Multiple lines can be written by synchronizing on this object and using setServiceAutoDumpErr to temporarily turn off auto-logging, as shown in the following example:

synchronized (err)
{
boolean oldautodump = setServiceAutoDumpErr(false);
err.println("Line 1");
err.println("Line 2");
setServiceAutoDumpErr(oldautodump);
err.flush();
