};DESCRIPTION
An nng_sockaddr is a structure used for
representing the addresses used by underlying transports, such as TCP/IP
addresses, IPC paths, and so forth.
This structure is actually a union, with different members for different types of addresses.
Every member structure has as its first element a uint16_t field
containing the “address family”.
This overlaps the s_family member of the union, and indicates which
specific member should be used.
The values of s_family are as follows:
NNG_AF_UNSPEC
|
Invalid address, no other valid fields. |
NNG_AF_INPROC
|
Address for intraprocess communication (nng_inproc(7)). The |
NNG_AF_IPC
|
Address for interprocess communication (nng_ipc(7)). The |
NNG_AF_INET
|
Address for TCP/IP (v4) communication. The |
NNG_AF_INET6
|
Address for TCP/IP (v6) communication. The |
NNG_AF_ZT
|
Address for ZeroTier transport (nng_zerotier(7)). The |
Please see the manual pages for each individual type for more information.
