c\c++ 中字符串分割，并且转换为整形数据

　　在项目开发中，经常使用到字符串分割， 并且将其转换为整形（比如IP的分割获取，MAC地址的分割获取等），代码如下：

#ifndef _UNICODE
    void StrToIntData( char *pStr,int nIntData[],const char * pTok )
    {

        char *pStrPos = NULL;
        char *pNextToken = NULL;
        int nPos = 0;

        pStrPos = strtok_s(pStr,pTok,&pNextToken);

        while (pStrPos) 
        {
            nIntData[nPos] = atoi(pStrPos);
            nPos ++;
            pStrPos = strtok_s(NULL,pTok,&pNextToken);
        } 

    }

    char * IntToStrData(int nData)
    {
        static char str[MAX_PATH] = {0};
        itoa(nData,str,10); 
        return str;
    }

#else
    void StrToIntData( wchar_t *pStr,int nIntData[],const wchar_t * pTok )
    {

        wchar_t *pStrPos = NULL;
        wchar_t *pNextToken = NULL;
        int nPos = 0;

        pStrPos = wcstok_s(pStr,pTok,&pNextToken);

        while (pStrPos) 
        {
            nIntData[nPos] = _ttoi(pStrPos);
            nPos ++;
            pStrPos = wcstok_s(NULL,pTok,&pNextToken);
        } 

    }

    wchar_t * IntToStrData(int nData)
    {
        static  wchar_t str[MAX_PATH] = {0};
        _itot(nData,str,10); 
        return str; 
    }
