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.

The _ival_ +is passed to the option. For booleans pass either 0 (false) or 1 (true). + +The third form, `nng_dialer_setopt_ms()`, is used to configure time durations +(such as timeouts). +The duration _dur_ is an integer number of milliseconds. (The special value +`NNG_DUR_INFINITE` means an infinite amount of time.) + +The fourth form, `nng_dialer_setopt_ptr()`, is used to pass a +pointer _ptr_ to structured data. The data referenced by _ptr_ is +generally managed by other functions. +For example, TLS configuration objects +(<>) can be passed this way. +Note that this form is somewhat special in that the object is generally +not copied, but instead the *pointer* to the object is copied. + +The fifth form, `nng_dialer_setopt_size()`, is used to pass a size +specified by _z_, typically for buffer sizes, message maximum sizes, and +similar options. + +The sixth form, `nng_dialer_setopt_string()`, is used to pass a string +_str_. +Strings passed this way must be legal UTF-8 or ASCII strings, terminated +with a `NUL` (`\0`) byte. +(Other constraints may apply as well, see the +documentation for _opt_ for details.) + +The seventh form, `nng_dialer_setopt_uint64()`, is used to configure +the 64-bit unsigned value in _u64_. +This is typically used for options +related to identifiers, network numbers, and similar. + +NOTE: Once a dialer has started, it is generally not possible to change +it's configuration. + +== RETURN VALUES + +This function returns 0 on success, and non-zero otherwise. + +== ERRORS + +`NNG_ECLOSED`:: Parameter _d_ does not refer to an open dialer. +`NNG_EINVAL`:: The value being passed is invalid. +`NNG_ENOTSUP`:: The option _opt_ is not supported. +`NNG_EREADONLY`:: The option _opt_ is read-only. +`NNG_ESTATE`:: The dialer _d_ is already started. + +== SEE ALSO + +<> +<> +<>, +<>, +<>, +<> -- cgit v1.2.3-70-g09d2
