[Qt-interest] How to get unicode data from socket?

[Alex]

Hi, all,


Thanks for all people answered the question.

Due to the data are unicode string.
Plus, the data is sent by a third party non-QT based application.
So I don't think QDataStream can fit my requirement.

Now, I know I should use fromUtf16() to convert it.
But, its prototype is *fromUtf16(const ushort* unicode, int size=-1)*
and I can't find a way to convert a ByteArray to a pointer of ushort.

Moveover, anyone knows an alternative of memcpy()?


Thanks.
Alex
