cannot read correct len from socket

[saman_artorious]

I am sending a QByteArray from server to client. the client needs to extract the first four bytes for length of packet and then read the rest of the packet. The unexpected value I get from length of packet though, is a very large value;
what I do is:

int len;
char *data;
 
client.read((char*)len, 4); // read the first integer for the length
client.read(data, len);

int len;
char *data;

client.read((char*)len, 4); // read the first integer for the length
client.read(data, len);

can anyone guess what the problem is?
