使用方式：

#include 
using namespace std;
#include "base_queue.h"
//流程 初始化向空的PutEmptyBuf 
//使用:GetEmptyBuf ->PutFullBuf ->GetFullBuf ->PutEmptyBuf
int main()
{
	int nRet = 0;
	BaseQueue qe;
	
	int *pA = new int;
	memset(pA, 0, sizeof(int));
	qe.PutEmptyBuf(pA);


	void *pTmp1 = NULL;
	qe.GetEmptyBuf(&pTmp1);

	*(int*)pTmp1 = 1;
	qe.PutFullBuf(pTmp1);

	int nCount = 0;
	qe.GetFullBufCount(&nCount);


	void *pTmp11 = NULL;
	nRet = qe.GetFullBuf(&pTmp11);
	if (nRet != 0)
	{
		//error
	}
	int value = *(int*)pTmp11;

	qe.PutEmptyBuf(pTmp11);


	return 0;
}
