* \brief Copies src file to dst file.
*
* If the dst file is open, it must be open for writing.
* If the src file is open, if must be open for reading.
*
* The files will be in the same open or close state after
* this function runs as they were prior to this function being called.
*
* This function does not care if the files are actual files.
* For compatibility with pipes and socket streams the file location
* will not be reset to 0 at the end of this function. If the function
* is successful the file pointers will be at the end of the copied
* data.
*
* \param dst Destination QFile
* \param src Source QFile
* \param block_size Optional block size in bytes, must be at least 1024,
* otherwise the default of 16 KB will be used.
* \return bytes copied on success, -1 on failure.
