1. 获得进程的nice值

int getpriority(int which, int who);

#include<stdio.h>
#include<sys/resource.h>
#include<errno.h>
#include<string.h>
int main()
{
    errno = 0;
    int p = getpriority(PRIO_PROCESS, 0);
    if(p == -1 && errno != 0)
    {
        printf("get priortiy fail,error:[%s]\n", strerror(errno));
        return;
    }
    printf("get ok, prio=[%d]\n", p);
}
[liudong2@hebe21 test]$ ./tpriority 
get ok, prio=[-4]
