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