timeval结构不正确? [英] timeval struct incorrect?

问题描述

timeval结构未由opengroup定义，请参见http://www.opengroup.org/onlinepubs/007908799/xsh/systime.h.html .在Windows 64位上，time_t为64位，长为32位. timeval结构应使用time_t，否则将来随着时间的推移也会出现问题.

The timeval struct is not defined as by the opengroup, see http://www.opengroup.org/onlinepubs/007908799/xsh/systime.h.html. time_t is 64bit on windows 64bit, long is 32bit. The timeval struct should use time_t, else we also get a problem in the future with time.

推荐答案

我也遇到了这个问题.我的应用程序广泛使用Timeval结构，并将其用于对localtime()等的调用. ].它在VC6中工作，因为其中的Time_t类型很长.但是现在，它在 VC8，因为VC8中的Time_T类型为__int64.它编译成功，但在运行时崩溃.

I am also facing this problem. My application uses Timeval structure extensively and uses it in calls to localtime() etc. [eg : struct tm *ttm = localtime(&(tv.tv_sec)); ]. It works in VC6 as type of Time_t was long in it. But now, it does not work in VC8, as type of Time_T in VC8 is __int64.  It compiles successfully, but crashes at runtime.

 

是否有正确的时间结构定义?

Is a correct definition of timeval structure available?
