| 58 | <H2>DESCRIPTION</H2> | |
| 59 | ||
| 60 | These functions fill in, and test for, special values of the | |
| 61 | <I>ip_address</I> | |
| 62 | ||
| 63 | type. | |
| 64 | <P> | |
| 65 | ||
| 66 | <I>Anyaddr</I> | |
| 67 | ||
| 68 | fills in the destination | |
| 69 | <I>*dst</I> | |
| 70 | ||
| 71 | with the ``any'' address of address family | |
| 72 | <I>af</I> | |
| 73 | ||
| 74 | (normally | |
| 75 | <B>AF_INET</B> | |
| 76 | ||
| 77 | or | |
| 78 | <B>AF_INET6</B>). | |
| 79 | ||
| 80 | The IPv4 ``any'' address is the one embodied in the old | |
| 81 | <B>INADDR_ANY</B> | |
| 82 | ||
| 83 | macro. | |
| 84 | <P> | |
| 85 | ||
| 86 | <I>Isanyaddr</I> | |
| 87 | ||
| 88 | returns | |
| 89 | <B>1</B> | |
| 90 | ||
| 91 | if the | |
| 92 | <I>src</I> | |
| 93 | ||
| 94 | address equals the ``any'' address, | |
| 95 | and | |
| 96 | <B>0</B> | |
| 97 | ||
| 98 | otherwise. | |
| 99 | <P> | |
| 100 | ||
| 101 | Similarly, | |
| 102 | <I>unspecaddr</I> | |
| 103 | ||
| 104 | supplies, and | |
| 105 | <I>isunspecaddr</I> | |
| 106 | ||
| 107 | tests for, | |
| 108 | the ``unspecified'' address, | |
| 109 | which may be the same as the ``any'' address. | |
| 110 | <P> | |
| 111 | ||
| 112 | Similarly, | |
| 113 | <I>loopbackaddr</I> | |
| 114 | ||
| 115 | supplies, and | |
| 116 | <I>islookbackaddr</I> | |
| 117 | ||
| 118 | tests for, | |
| 119 | the loopback address. | |
| 120 | <P> | |
| 121 | ||
| 122 | <I>Anyaddr</I>, | |
| 123 | ||
| 124 | <I>unspecaddr</I>, | |
| 125 | ||
| 126 | and | |
| 127 | <I>loopbackaddr</I> | |
| 128 | ||
| 129 | return | |
| 130 | <B>NULL</B> | |
| 131 | ||
| 132 | for success and | |
| 133 | a pointer to a string-literal error message for failure; | |
| 134 | see DIAGNOSTICS. | |
