| 52 | /* Converts an internet address from internal format to a printable, |
| 53 | presentable format. |
| 54 | AF is an internet address family, such as AF_INET or AF_INET6. |
| 55 | SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr' |
| 56 | (for AF_INET6). |
| 57 | DST points to a buffer having room for CNT bytes. |
| 58 | The printable representation of the address (in numeric form, not |
| 59 | surrounded by [...], no reverse DNS is done) is placed in DST, and |
| 60 | DST is returned. If an error occurs, the return value is NULL and |
| 61 | errno is set. If CNT bytes are not sufficient to hold the result, |
| 62 | the return value is NULL and errno is set to ENOSPC. A good value |
| 63 | for CNT is 46. |
