Re: sscanf question

Hi,

The following is the piece of code I'm using, and it's output.

Thanks,

Andre


#include <stdio.h>

char buf1[] = "c0a80174.13e1;received=207.81.158.209\r\nVia:

char buf2[] = "z9hG4bK3c36655c;rport\r\nFrom: \"asterisk\"

int main()
{
int ip = 0;
int port = 0;

sscanf(buf1, "%x.%x", &ip, &port);
printf("buf1: ip=%d port=%d\n", ip, port);

ip = 0;
port = 0;

sscanf(buf2, "%x.%x", &ip, &port);
printf("buf2: ip=%d port=%d\n", ip, port);

return 0;
}

Output:

buf1: ip=-1062731404 port=5089
buf2: ip=0 port=0
