Function genClientAddrString

src/networking.cpp:2837–2846

A Redis "Address String" is a colon separated ip:port pair. * For IPv4 it's in the form x.y.z.k:port, example: "127.0.0.1:1234". * For IPv6 addresses we use [] around the IP part, like in "[::1]:1234". * For Unix sockets we use path:0, like in "/tmp/redis:0". * * An Address String always fits inside a buffer of NET_ADDR_STR_LEN bytes, * including the null term. * * On failure the function

 * you want to relax error checking or need to display something anyway (see
 * anetFdToString implementation for more info). */
