| 50 | ||
| 51 | These functions are obsolete; see | |
| 52 | <I><A HREF="ipsec_networkof.3.html">ipsec_networkof</A></I>(3) | |
| 53 | ||
| 54 | for their replacements. | |
| 55 | <P> | |
| 56 | ||
| 57 | <I>Subnetof</I> | |
| 58 | ||
| 59 | takes an Internet | |
| 60 | <I>address</I> | |
| 61 | ||
| 62 | and a subnet | |
| 63 | <I>mask</I> | |
| 64 | ||
| 65 | and returns the network part of the address | |
| 66 | (all in network byte order). | |
| 67 | <I>Hostof</I> | |
| 68 | ||
| 69 | similarly returns the host part, and | |
| 70 | <I>broadcastof</I> | |
| 71 | ||
| 72 | returns the broadcast address (all-1s convention) for the network. | |
| 73 | <P> | |
| 74 | ||
| 75 | These functions are provided to hide the Internet bit-munging inside | |
| 76 | an API, in hopes of easing the eventual transition to IPv6. | |
