C++ 字符串分割，分割到vector中

#include <string>
#include <vector>
using std::string;
using std::vector;

int splitStringToVect(const string & srcStr, vector<string> & destVect, const string & strFlag);

int main()
{
    string str = "asdasdas \n, sadasd\n, ssdddsrr\n \n \n ss\n";
    vector<string>   destVect;
    splitStringToVect(str, destVect, "\n");     //以"\n"为标记，分割字符串到vector中
    return 1;
}

int splitStringToVect(const string & srcStr, vector<string> & destVect, const string & strFlag)
{
    int pos = srcStr.find(strFlag, 0);
    int startPos = 0;
    int splitN = pos;
    string lineText(strFlag);

    while (pos > -1)
    {
        lineText = srcStr.substr(startPos, splitN);
        startPos = pos + 1;
        pos = srcStr.find(strFlag, pos + 1);
        splitN = pos - startPos;
        destVect.push_back(lineText);
    }

    lineText = srcStr.substr(startPos, srcStr.length() - startPos);
    destVect.push_back(lineText);
