i want use tcpsocket send a uchar data,, but there is no function conversion uchar to QByteArray

how can i use qtcpsocket send const unsigned char* src data ?

conversion to
QByteArray ?
QChar ?

Code:

---

this->m_tcpSocket = new QTcpSocket(this);
    this->tcpSocket->connectToHost("192.168.0.111",8888);
    connect(this->tcpSocket,SIGNAL(connected()),this,(sendData()));
 
sendData function
 
{
   const unsigned char* src = some unsigned char data
 
   this->tcpSocket->write(?,size) ?

Just cast it to a char

tcpSocket->write((char*)src, size);
