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