getaddrinfo error Wynne, Arkansas

I'm not attached to the port number or anything except the host. EAI_SERVICE The requested service is not available for the requested socket type. hints A pointer to an addrinfo structure that provides hints about the type of socket you're supporting. This flag prevents a name resolution service from being called.

Finally, the **res parameter is dereferenced to make it point to a newly allocated addrinfo structure.[3] In some implementations, such as the Unix version for Mac OS, the hints->ai_protocol overrides the Thanks for the info! –John Doucette Nov 15 '12 at 11:51 2 @JohnDoucette Using assignment inside conditions is a very effective way to generate hard-to-find bugs. –Lundin Nov 15 '12 If hints.ai_flags specifies the AI_V4MAPPED flag, and hints.ai_family was specified as AF_INET6, and no matching IPv6 addresses could be found, then return IPv4-mapped IPv6 addresses in the list pointed to by Downloads and tools Windows 10 dev tools Visual Studio Windows SDK Windows Store badges Essentials API reference (Windows apps) API reference (desktop apps) Code samples How-to guides (Windows apps) Learning resources

If the AI_PASSIVE flag is specified in hints.ai_flags, and node is NULL, then the returned socket addresses will be suitable for bind(2)ing a socket that will accept(2) connections. I located the hosts line and put dns in front of the mdns stuff, like so hosts: files dns mdns4_minimal [NOTFOUND=return] after that I could start avahi, and still do .local In each addrinfo structure the ai_addr member points to a filled-in socket address structure whose length is specified by the ai_addrlen member. For this method to work with an IPv6 address string on Windows Server 2003 and Windows XP, the IPv6 protocol must be installed on the local computer.

The AI_SECURE flag is defined on the Windows SDK for Windows Vista and later. Specifying 0 in this field indicates that socket addresses with any protocol can be returned by getaddrinfo(). The remaining fields of each returned addrinfo structure are initialized as follows: * The ai_family, ai_socktype, and ai_protocol fields return the socket creation parameters (i.e., these fields have the same meaning more hot questions question feed lang-c about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation

Why (in universe) are blade runners called blade runners? The AI_ADDRCONFIG flag is defined on the Windows SDK for Windows Vista and later. Then, if hostname is given (not NULL), a call to gethostbyname() resolves it, or otherwise the address is used, if hints->ai_flags is set to AI_PASSIVE, and otherwise. The list can be processed by following the pointer provided in the ai_next member of each returned addrinfo structure until a NULL pointer is encountered.

If the pNodeName parameter is a NULL pointer in this case, the IP address portion of the socket address structure is set to the loopback address. ai_flags This field specifies additional options, described below. EAI_NONAME The node or service is not known; or both node and service are NULL; or AI_NUMERICSERV was specified in hints.ai_flags and service was not a numeric port-number string. If the call succeeds, // the result variable will hold a linked list // of addrinfo structures containing response // information dwRetval = getaddrinfo(argv[1], argv[2], &hints, &result); if ( dwRetval !=

The AI_NON_AUTHORITATIVE flag is supported on Windows Vista and later and applies only to the NS_EMAIL namespace. EAI_NODATA The specified network host exists, but does not have any network addresses defined. vBulletin 2000 - 2016, Jelsoft Enterprises Ltd. Note that there aren't any hardcoded references to any particular address family; the code works even if getaddrinfo() returns addresses that aren't IPv4/v6.

AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES Setting these flags will enable the IDNA_ALLOW_UNASSIGNED (allow unassigned Unicode code points) and IDNA_USE_STD3_ASCII_RULES (check output to make sure it is a STD3 conforming hostname) flags respectively to be

The getaddrinfo() function is documented in RFC 2553. WSAEAFNOSUPPORT An address incompatible with the requested protocol was used. more hot questions question feed lang-c about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation The value AF_UNSPEC indicates that getaddrinfo() should return socket addresses for any address family (either IPv4 or IPv6, for example) that can be used with node and service.

service can be a port number passed as string, such as "80", or a service name, e.g. "echo". Not the answer you're looking for? AI_NUMERICSERV is available since glibc 2.3.4. If hints is not NULL it points to an addrinfo structure whose ai_family, ai_socktype, and ai_protocol specify criteria that limit the set of socket addresses returned by getaddrinfo(), as follows: ai_family

AI_ALL is ignored if AI_V4MAPPED is not also specified. Wikipedia® is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization. The AI_RETURN_PREFERRED_NAMES flag is defined on the Windows SDK for Windows Vista and later. It may be available through another socket type.

To return this information to the system the function Fn freeaddrinfo is called.

What do I do when two squares are equally valid? This error message occurs regardless of what GUI rdc interface I use (e.g. Avahi uses .local by default (see also ) It has also became a common practice to use .local for internal networks. The IdnToUnicode function converts the ASCII form of an IDN to the normal Unicode UTF-16 encoding syntax.
