|Subject:||Re: [lwip-users] Sending out TCP-Data as integer type|

What is sizeof(int) ?
From: address@hidden [mailto:address@hidden On Behalf Of Firedog I.
I got a little problem over here. I can send simple TCP-Data like string and char, but I can’t send data as integer type. I’m using lwIP v1.36 with RAW API.
/*Connection to Client established…*/
int data = "" //or int data = "">
tcp_write(pcb, data, 1, 1);
When sending this Packet out, I receive a “00” as data in Wireshark.
I’ve tried sending out the equal ASCII-char to 255, a “ÿ“ (see extended ASCII), and this one works. When sending out this char, Wireshark shows a TCP-Packet with 1 byte length and a "ff" as data. That’s exactly what I want, but I don’t want to convert integer vars into extended ascii and then send the converted data out.
Any suggestions how to solve the problem?
