Build LUA Module

ua
 && make install

Usage for LUA

ire("bbip");
= bbip.new("BBIP.dat");
preload()
i = 1, 10000000 do
-- return as multiple variables
range_start, range_end, country, province, city, district, isp, type, desc, lat, lng, cidr = bip:query("223.5.5.5")
print(range_start, range_end, country, province, city, district, isp, type, desc, lat, lng, cid)
-- return as a Lua Table
rc = bip:query_table("223.5.5.5")

Usage for C

lude <arpa/inet.h>
lude "bbip.h"

main(int argc, const char **argv)

bbip_t bbip;
int bbip_errno;
bbip_result_t *result;
struct in_addr addr;
FILE *fpData;

if (argc < 2) {
    printf("usage:\n");
    printf("  bbip_demo <ip>\n");
    return 1;
}
fpData = fopen("bbip.dat", "rb");
if (fpData == NULL) {
   fprintf(stderr, "Invalid data file\n");
   return 1;
}
if (bbip_init(&bbip, fpData, &bbip_errno) == NULL) {
   fprintf(stderr, "init bbip failed: %d\n", bbip_errno);
   return 1;
}
bbip_preload(&bbip);  // increase performance

inet_aton(argv[1], &addr);
result = bbip_search(&bbip, ntohl(addr.s_addr));
if (result != NULL) {
    printf("country: %.*s\n", result->country_len, result->country);
    printf("province: %.*s\n", result->province_len, result->province);
    printf("city: %.*s\n", result->city_len, result->city);
    printf("isp: %.*s\n", result->isp_len, result->isp);
    free(result);
}
