23 | /* Converts an internet address from internal format to a printable, | ||
24 | presentable format. | ||
25 | AF is an internet address family, such as AF_INET or AF_INET6. | ||
26 | SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr' | ||
27 | (for AF_INET6). | ||
28 | DST points to a buffer having room for CNT bytes. | ||
29 | The printable representation of the address (in numeric form, not | ||
30 | surrounded by [...], no reverse DNS is done) is placed in DST, and | ||
31 | DST is returned. If an error occurs, the return value is NULL and | ||
32 | errno is set. If CNT bytes are not sufficient to hold the result, | ||
33 | the return value is NULL and errno is set to ENOSPC. A good value | ||
34 | for CNT is 46. | ||
