Detailed Description

The IODevice class represents a buffer with independent read-write.

QBuffer has one position pointer, so when we write data, the position pointer points to the end of the buffer and no bytes can be read.

This class is interesting for all CMs that use a library that accepts a QIODevice for file transfers.

Note: This class belongs to the service library.

writeData()

qint64 Tp::IODevice::writeData ( const char *  data, qint64  maxSize  )

protected

Writes the data to the buffer.

Writes up to maxSize bytes from data to the buffer. If maxSize is not a zero, emits readyRead() and bytesWritten() signals.

Parameters

data	The data to write.
maxSize	The number for bytes to write.

Returns

The number of bytes that were written.
