说明:在使用gettimeofday()函数时,第二个参数一般都为空,因为我们一般都只是为了获得当前时间,而不用获得timezone的数值 gettimeofday() Get the currenttime Synopsis: #include <sys/time.h> int gettimeofday( structtimeval *when, void *not_used); Argument

可以看到,在__getnstimeofday里面拿到的两个值分别为Current CLOCK_REALTIME time in seconds(xtime_sec) 和 Clock shifted nano seconds(xtime_nsec)。 接下来,我们就得看下结构体timekeeper里面的数据是哪里来的? timekeeping初始化代码在timekeeping_init中,在系统初始化的时候(start_kernel)会调用该函数进行timekeep...

1.从配置文件中读取各个配置项的值 该操作的流程具体请参见《Linux下配置文件读取操作流程及其C代码实现》 2.获取当前的系统时间 在本程序示例中,我们使用系统自带的gettimeofday和localtime函数来获取Linux机器的当前时间。 (1)gettimeofday函数的定义为:
GetCurrentProcess 和 GetCurrentThread:用于获取当前进程和线程的句柄。 CreateThread 和 ExitThread:用于创建和退出线程。 Sleep 和 WaitForSingleObject:用于控制线程的等待和延迟。 4.动态链接库(DLL)相关的函数和宏: LoadLibrary 和 FreeLibrary:用于加载和释放 DLL。
