以下代码用于打印日志中的时间:
The following piece of code is used to print the time in the logs:
#define PRINTTIME() struct tm * tmptime;
time_t tmpGetTime;
time(&tmpGetTime);
tmptime = localtime(&tmpGetTime);
cout << tmptime->tm_mday << "/" <<tmptime->tm_mon+1 << "/" << 1900+tmptime->tm_year << " " << tmptime->tm_hour << ":" << tmptime->tm_min << ":" << tmptime->tm_sec<<">>";
有什么办法可以增加毫秒数吗?
Is there any way to add milliseconds to this?
要获得毫秒级精度,您必须使用特定于您的操作系统的系统调用.
To have millisecond precision you have to use system calls specific to your OS.
在Linux中你可以使用
In Linux you can use
#include <sys/time.h>
timeval tv;
gettimeofday(&tv, 0);
// then convert struct tv to your needed ms precision
timeval
具有微秒精度.
在 Windows 中,您可以使用:
In Windows you can use:
#include <Windows.h>
SYSTEMTIME st;
GetSystemTime(&st);
// then convert st to your precision needs
当然,您可以使用 Boost 为您做到这一点:)
Of course you can use Boost to do that for you :)
