关于加解锁的两种实现方式
方案一：使用C++11 atomic_flag原子特性实现细粒度加解锁
#ifndef YAGER_MUTEX_H
#define YAGER_MUTEX_H
#include <atomic>
class CYagerMutex
{
public:
CYagerMutex()
: m_atomicFlag(ATOMIC_FLAG_INIT)
{}
~CYagerMutex()
{}
void Lock()
{
while (m_atomicFlag.test_and_set());
}
void UnLock()
{
m_atomicFlag.clear();
}
private:
std::atomic_flag m_atomicFlag;
};
#endif //YAGER_MUTEX_H
方案二：使用libuv的mutex，实现粗粒度的加解锁
#include "libuv/include/uv.h"
class CYagerMutex
{
public:
CYagerMutex()
{
uv_mutex_init(&m_mutex);
}
~CYagerMutex()
{
uv_mutex_destroy(&m_mutex);
}
void Lock()
{
uv_mutex_lock(&m_mutex);
}
void UnLock()
{
uv_mutex_unlock(&m_mutex);
}
private:
uv_mutex_t m_mutex;
};
