From 98f23e10cc1d65da6a7f6c7e4f5665d7afc27a86 Mon Sep 17 00:00:00 2001 From: Garrett D'Amore Date: Thu, 15 Mar 2018 08:40:17 -0700 Subject: fixes #286 nng_pair0_open (and all others) need man page fixes #279 consider restructuring man sections This represents a rather significant rework, and major editing effort, for the entire set of manual pages. All of the pages now have a section number in their filename; this assists in some other tooling, particularly ebook generation as every link needs to be programmatically modified when combined into an ebook. Section 5 is introduced, and populated with pages for the main types, and all options are now documented. Numerous errors have been corrected, including rewriting certain portions such as the header section of the surveyor protocol. Much work has been done to facilitate index generation, although certainly more work remains here. Every internal link within these pages now resolves; there are no more dead links. (This is required to generate Kindle format books.) --- docs/man/nng_tcp.adoc | 115 -------------------------------------------------- 1 file changed, 115 deletions(-) delete mode 100644 docs/man/nng_tcp.adoc (limited to 'docs/man/nng_tcp.adoc') diff --git a/docs/man/nng_tcp.adoc b/docs/man/nng_tcp.adoc deleted file mode 100644 index ad615e11..00000000 --- a/docs/man/nng_tcp.adoc +++ /dev/null @@ -1,115 +0,0 @@ -= nng_tcp(7) -// -// Copyright 2018 Staysail Systems, Inc. -// Copyright 2018 Capitar IT Group BV -// -// This document is supplied under the terms of the MIT License, a -// copy of which should be located in the distribution where this -// file was obtained (LICENSE.txt).

Both IPv4 and IPv6 -are supported when the underlying platform also supports it. - -// We need to insert a reference to the nanomsg RFC. - -=== Registration - -The _tcp_ transport is generally built-in to the _nng_ core, so -no extra steps to use it should be necessary. - -=== URI Format - -This transport uses URIs using the scheme `tcp://`, followed by -an IP address or hostname, followed by a colon and finally a -TCP port number. For example, to contact port 80 on the localhost -either of the following URIs could be used: `tcp://127.0.0.1:80` or -`tcp://localhost:80`. - -When specifying IPv6 addresses, the address must be enclosed in -square brackets (`[]`) to avoid confusion with the final colon -separating the port. - -For example, the same port 80 on the IPv6 loopback address ('::1') would -be specified as `tcp://[::1]:80`. - -NOTE: When using symbolic names, the name is resolved when the -name is first used. _nng_ won't become aware of changes in the -name resolution until restart, -usually.footnote:[This is a bug and will likely be fixed in the future.] - -The special value of 0 (`INADDR_ANY`) can be used for a listener -to indicate that it should listen on all interfaces on the host. -A short-hand for this form is to either omit the address, or specify -the asterisk (`*`) character. For example, the following three -URIs are all equivalent, and could be used to listen to port 9999 -on the host: - - 1. `tcp://0.0.0.0:9999` - 2. `tcp://*:9999` - 3. `tcp://:9999` - -The entire URI must be less than `NNG_MAXADDRLEN` bytes long. - -=== Socket Address - -When using an `nng_sockaddr` structure, the actual structure is either -of type `nng_sockaddr_in` (for IPv4) or `nng_sockaddr_in6` (for IPv6). -These are `struct` types with the following definitions: - -[source,c] --------- -#define NNG_AF_INET 3 <1> -#define NNG_AF_INET6 4 -#define NNG_MAXADDRLEN 128 - -typedef struct { - // ... <2> - uint16_t sa_family; // must be NNG_AF_INET - uint16_t sa_port; // TCP port number - uint32_t sa_addr; - // ... -} nng_sockaddr_in; - -typedef struct { - // ... <2> - uint16_t sa_family; // must be NNG_AF_INET6 - uint16_t sa_port; // TCP port number - uint8_t sa_addr[16]; - // ... -} nng_sockaddr_in6; --------- -<1> The values of these macros may change, so applications -should avoid depending upon their values and instead use them symbolically. -<2> Other members may be present, but only those listed here -are suitable for application use. - -The `sa_family` member will have the value `NNG_AF_INET` or `NNG_AF_INET6`. -The `sa_port` and `sa_addr` are the TCP port number and address, both in -network byte order (most significant byte is first). - -=== Transport Options - -The _tcp_ transport has no special -options.footnote:[Options for TCP keepalive, linger, and nodelay are planned.] - -== SEE ALSO - -<> -- cgit v1.2.3-70-g09d2
