C++ 中如何将文本的16进制读取到内存

Question

像这一种数据格式的字符串怎么转换，因为这一段需要动态调用。在网上找了好多没找到解决方法，求帮助

我自己写了个函数解决了，效果图

void* Buf16ToMem16(string sBuf)
{
string strBuf = sBuf;
string strtmp ;
DWORD dwSt=0,dwEd=0,dwCount=0,dwStrSz = 0;
BYTE* bTmp = new BYTE{0};
void* TmpVoid;
void* RetVoid;

dwStrSz = strBuf.size();
dwSt = strBuf.find("\\", dwSt ? dwSt + 1 : 0);
TmpVoid = new char[dwStrSz] {0};
while (true)
{
    dwEd = strBuf.find("\\", dwSt + 1);
    strtmp = strBuf.substr(dwSt + 1, (dwEd - dwSt - 1));
    sscanf_s(strtmp.c_str(), "x%x", &bTmp);
    memcpy_s((char*)TmpVoid +dwCount, 1, &bTmp, 1);

    if (dwEd == string::npos)
    {
        break;
    }

    ++dwCount;
    dwSt = dwEd;

}
RetVoid = new char[dwCount + 1]{0};
memcpy_s(RetVoid, dwCount + 1, TmpVoid, dwCount + 1);
delete TmpVoid;
TmpVoid = NULL;
return RetVoid;

}
