Returns the number of bytes that are available for reading.
This function is commonly used with sequential devices to determine the number of bytes to allocate in a buffer before reading.
Subclasses that reimplement this function must call the base implementation in order to include the size of QIODevices' buffer. Example:
Reimplemented from QIODevice.

Referenced by readData().

virtual |
Closes this device for reading.
Unread data is discarded, but the network resources are not discarded until they are finished. In particular, if any upload is in progress, it will continue until it is done.
The finished() signal is emitted when all operations are over and the network resources are freed.

For open random-access devices, this function returns the size of the device.
For open sequential devices, bytesAvailable() is returned.
If the device is closed, the size returned will not reflect the actual size of the device.
