2 | * Replacement for a missing or broken inet_ntoa. |
---|
3 | * |
---|
4 | * Provides the same functionality as the standard library routine inet_ntoa |
---|
5 | * for those platforms that don't have it or where it doesn't work right (such |
---|
6 | * as on IRIX when using gcc to compile). inet_ntoa is not thread-safe since |
---|
7 | * it uses static storage (inet_ntop should be used instead when available). |
