u_char* to QDataStream and readDouble() in the stream
I'm trying to parse TCP Packets that comes in the form of u_char*
But I haven't found a way to do it
What I'm looking for is the same behavior as stream.readDouble() in c# so that I can parse different values from the packets without iterating through the u_char*
To be more specific I'll give an example of the data I want to parse
This is the packet with like multiple values in it [int][utf text][double][u_short]
And I want something like
int i = stream.readInt(); char *text = stream.readUTF8(); double number = stream.readDouble(); u_short tinyNumber = stream.readUShort();
Is this possible?
int i; QString text; double number; u_short tinyNumber; stream >> i >> text >> number >> tinyNumber;
Out of curiosity, where are these packets coming from ?
You can use @jsulm solution for all the types* apart for the text. You need to tell us how you can determine when the text finishes. Is it null terminated? does it have a header that tells you the size?
* You should be careful with endianness but since you are saying it comes from TCP it's fair to assume the usual Big-Endian convention
