一个简单的stl中string的split函数

int SplitString(const string &srcStr,const string &splitStr,vector<string> &destVec)
{
    if(srcStr.size()==0)
    {   
        return 0;
    }   
    size_t oldPos,newPos;
    oldPos=0;
    newPos=0;
    string tempData;
    while(1)
    {   
        newPos=srcStr.find(splitStr,oldPos);
        if(newPos!=string::npos)
        {   
            tempData = srcStr.substr(oldPos,newPos-oldPos);
            destVec.push_back(tempData);
            oldPos=newPos+splitStr.size();
        }   
        else if(oldPos<=srcStr.size())
        {   
            tempData= srcStr.substr(oldPos);
            destVec.push_back(tempData);
            break;
        }   
        else
        {   
            break;
        }   
    }   
    return 0;
}

string src = ",,w,,ai,,,nio,,";
string splitStr = ",,";
vector<string> destVec;
 
SplitString(src,splitStr,destVec);
for(vector<string>::iterator it = destVec.begin();it!=destVec.end();++it)
