Size of data in the write buffer waiting for writing.

Uint2 m_RdSize

Size of data available for reading in the read buffer.

bool NeedEarlyClose(void)

void x_PrintError(void)

Prints socket's error if there's any error pending on the socket.

CSrvSocketTask & WriteBool(bool b)

bool FlushIsDone(void)
