Further refined as

Even more:

memcpy(&tmpBuffer[0], &iReq, sizeof(iReq) );
memcpy(&tmpBuffer[0 + sizeof(iReq)], &strGetName, strlen(strGetName) );

if (tmpBuffer)

  memcpy(&tmpBuffer[0], &iReq, sizeof(iReq) );
  memcpy(&tmpBuffer[0 + sizeof(iReq)], &strGetName, strlen(strGetName) );
}
...
...
if (tmpBuffer) delete [] tmpBuffer;

Why is that. I know that sizeof(int) also gives the number 4. But why I can't use number 4 directly. Any special reason.

::memcpy(tmpBuffer, &iReq, 4);
::memcpy(tmpBuffer, &strGetName, 6);

// complexities left to reader
memcpy(tmpBuffer, &iReq, 4);
memcpy(tmpBuffer+4, strGetName, 6);

Any way pointing the buffer make correction to me, as on my second post. It is ok, right....
