用 times 函数:
times - get process and child process times
SYNOPSIS
#include
#include
clock_t times(struct tms *buffer);
DESCRIPTION
The times() function fills the tms structure pointed to by
buffer with time-accounting information. The tms structure,
defined in , contains the following members:
clock_t tms_utime;
clock_t tms_stime;
clock_t tms_cutime;
clock_t tms_cstime;
在调用函数前获取一下,在调用后获取一下。
