pcap problem

Show all headers | View raw

    This is the code I have so far and I run into a segmentation fault. The 
debugger says it has something to do with "activate".

#include <stdio.h>
#include <pcap/pcap.h>
#include <stdlib.h>

int main()
{
    pcap_t *pp;
    char *perr;
    int stat;
    int datalink;
    char errbuf[PCAP_ERRBUF_SIZE];
    pp = pcap_create("handle", errbuf);
    if (pp = NULL) {
        fputs(errbuf, stderr);
        exit(1);
    }
    stat = pcap_activate(pp);
    if (stat != 0) {
        perr = pcap_geterr(pp);
        printf("%s\n", perr);
        exit(1);
    }
    datalink = pcap_datalink(pp);
    if (datalink = PCAP_ERROR_NOT_ACTIVATED) {
        fputs("not activated error\n", stderr);
        exit(1);
    }
    puts("fine");
    return 0;
}
