[PyQt] Missing QIODevice::read overloads

[Florian Bruhin]

Hi,

I noticed the following QIODevice overloads are missing in PyQt:

    qint64 QIODevice::read(char * data, qint64 maxSize)
    qint64 QIODevice::readLine(char * data, qint64 maxSize)

only the following are available:

    QByteArray QIODevice::read(qint64 maxSize)
    QByteArray QIODevice::readLine(qint64 maxSize = 0)

The issue with those is that it's impossible to check for errors:

    This function has no way of reporting errors; returning an empty
    QByteArray can mean either that no data was currently available
    for reading, or that an error occurred.

The best workaround I found so far is to check if
QIODevice::errorString is "Unknown error", but that's a hack...

Maybe PyQt should provide the two other forms as well, when passing a
mutable byte object (QByteArray/bytearray?) as first parameter?

Thanks,

Florian
