环境 windows10 + vmware + archlinux
Intro
第一个程序cpu.c
就编译失败,原因是有一句 #include "common.h"
,随便网上搜了一下,找到了这个文件,抄进去之后编译成功。
common.h
#ifndef __common_h__
#define __common_h__
#include <sys/time.h>
#include <assert.h>
#include <pthread.h>
double
GetTime()
{
struct timeval t;
int rc = gettimeofday(&t, NULL);
assert(rc == 0);
return (double)t.tv_sec + (double)t.tv_usec/1e6;
}
void
Spin(int howlong)
{
double t = GetTime();
while((GetTime() - t) < (double)howlong)
; // do nothing in loop
}
void
Pthread_create(pthread_t *t, const pthread_attr_t *attr,
void *(*start_routine)(void *), void* arg) {
int rc = pthread_create(t, attr, start_routine, arg);
assert(rc == 0);
}
void
Pthread_join(pthread_t thread, void **value_ptr) {
int rc = pthread_join(thread, value_ptr);
assert(rc == 0);
}
void
Pthread_mutex_lock(pthread_mutex_t *mutex) {
int rc = pthread_mutex_lock(mutex);
assert(rc == 0);
}
void
Pthread_mutex_unlock(pthread_mutex_t *mutex) {
int rc = pthread_mutex_unlock(mutex);
assert(rc == 0);
}
void
Pthread_mutex_init(pthread_mutex_t *mutex, pthread_mutexattr_t *attr) {
int rc = pthread_mutex_init(mutex, attr);
assert(rc == 0);
}
#endif // __common_h__
正常运行,但是在控制台按Ctrl+C无法终止。 解决方法:执行ps -ef | grep cpu
找到你的程序的pid,然后执行kill pid1 pid2 ...
结束进程。
