GeoIP C API （Linux下使用）

This API should work on most UNIX and GNU/Linux platforms and is thread-safe. ./configure make make check make install For installing on Windows, see the READMEwin32.txt file supplied with the distribution. Usage This following sample code looks up the country code by IP address: #include int main (int argc, char *argv[]) { GeoIP * gi; gi = GeoIP_new(GEOIP_STANDARD); printf("code %s\n", GeoIP_country_code_by_name(gi, "yahoo.com")); } To compile this example, run gcc -lGeoIP example.c. *argv[]) { GeoIP * gi; gi = GeoIP_new(GEOIP_STANDARD); printf("code %s\n", GeoIP_country_code_by_name(gi, "yahoo.com")); } To compile this example, run gcc -lGeoIP example.c.
