problem with memcpy

[sattu]

First:

void *

void *

To copy to clipboard, switch view to plain text mode 

Is not a character array.

A question. What is the ultimate goal to put an object into a "character array"? What are you trying to achieve?
Please also define character array. Is this like a string?

Well tbscope, leave that example which i gave there. Actually, the thing is that i have a structure and some fields in it. So, now i need to copy all the contents of the structure to any array (may be QByteArray or Character array). But well, i have not been able to do it upto now. Leave the problem of memcpy, because that's not working. Can you suggest any other way of doing this copy?

With regards,

If you don't care about the ultimate size of the serialization, use QDataStream. If you do care then use QDataStream and then compress the resulting array using qCompress(). You'll get a byte array that you can send via a network link and then reverse the operation to receive the original structure.

O.k, fine. Actually my friend is trying with QDataStream, but is getting so many errors, due to lack of proper knowledge of exact syntax. Let me try more with it, and see what i get.

Hi wysota!
can you suggest me some qt examples where they have used the concept of QDataStream to serialize the required datas and then store it in a qbytearray?
Because i'm not able to get the basic idea regarding the it's use, so an example would do much better. So, can you just send me some useful examples?

You should overload << operator and let the structure serialise itself. That way if you use different compiler/architecture, you don't have to worry about how the structure is formed in memory.

There is an example in QDataStream docs. It's using QFile as the carrier but you can also pass it a byte array pointer.
