streamWrapper::stream_read — Read from stream
Remember to update the read/write position of the stream (by the number of bytes that were successfully read).
How many bytes of data from the current position should be returned.
If there are less than count bytes available, return as many as are available. If no more data is available, return either FALSE or an empty string.
Emits E_WARNING if call to this method fails (i.e. not implemented).
If the return value is longer then count an E_WARNING error will be emitted, and excess data will be lost.
streamWrapper::stream_eof() is called directly after calling streamWrapper::stream_read() to check if EOF has been reached. If not implemented, EOF is assumed.
