#if defined(HAVE_TIMES)
#include <unistd.h>
static double cycles_diff(struct tms *a,struct tms *b)
{
clock_t aa = a->tms_utime +
a->tms_stime +
a->tms_cutime +
a->tms_cstime;
clock_t bb = b->tmstms_utime
+ b->tms_stime
+ b->tms_cutime
+ b->tms_cstime;
return (aa-bb)/(double)sysconf(_SC_CLK_TCK);
}
}
这会带来错误
incomplete type declaration of struc tms
和
sysconf was not declared
最佳答案
According to the manual您需要#include <sys/times.h>
关于time - 无法使用struct tms编译代码,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/6840695/
