spin_lock.h从windows到linux的端口

Question

我有以下标题：

#if !defined(_SPIN_LOCK_H_INCLUDED_)
#define _SPIN_LOCK_H_INCLUDED_

#include <windows.h>

class spin_lock
{
public:
    spin_lock();
    virtual ~spin_lock();

    void lock( void );
    void unlock( void );

private:
    CRITICAL_SECTION m_lock;

    spin_lock( const spin_lock& that );
    const spin_lock& operator = ( const spin_lock& that );
};

有可能在Linux上以最小的更改移植它吗？

我发表评论后发现此错误：

在../sources/utils.11.0/MyPDFLibUtils.cpp:43:0中包含的文件中：     ../sources/utils.11.0/spin_lock.h:39:2：错误：'CRITICAL_SECTION'没有命名类型       CRITICAL_SECTION m_lock;

CRITICAL_SECTION在Microsoft SDK的WinBase.h部分中声明

这是实施：

#include <windows.h>

#include "spin_lock.h"

spin_lock::spin_lock()
{
    ::InitializeCriticalSection( &m_lock );
}

spin_lock::~spin_lock()
{
    ::DeleteCriticalSection( &m_lock );
}

void spin_lock::lock( void )
{
    ::EnterCriticalSection( &m_lock );
}

void spin_lock:: unlock( void )
{
    ::LeaveCriticalSection( &m_lock );
}
