Homebrew, iTerm2, and Sublime Text are probably your best bets out of the 32 options considered. 'Quick access to a large repository of open source software' is the primary reason people pick Homebrew over the competition. This page is powered by a knowledgeable community that helps you make an informed decision. Hi I have a long running service. When it receives a request from clients, it forks and execs a different binary to service the request. That new process sometimes failes in getaddrinfo with EAIAGAIN. Before OS X 10.5 the DNS system was a mix of new Mac OS X features, mDNSResponder and Open Directory, along with historical lookupd from NeXT and libresolv from an old BSD. In 10.5 the system was cleaned up to depend on OS X's mDNSResponder consistently; in the process getaddrinfo became thread-safe. See getaddrinfo(3) Mac OS X Developer Tools Manual Page and getnameinfo(3) Mac OS X Developer Tools Manual Page. Note: In iOS 9 and OS X 10.11 and later, NSURLSession and CFNetwork automatically synthesize IPv6 addresses from IPv4 literals locally on devices operating on DNS64/NAT64 networks. The getaddrinfo function combines the functionality provided by the gethostbyname(3) and getservbyname(3) functions into a single interface, but unlike the latter functions, getaddrinfo is reentrant and allows programs to eliminate IPv4-versus-IPv6 dependencies. The addrinfo structure used by getaddrinfo contains the following fields.
The functionsgetaddrinfo() and getnameinfo() convert domain names, hostnames, and IP addresses between human-readable text representations and structured binary formats for the operating system's networking API. Both functions are contained in the POSIX standard application programming interface (API).
getaddrinfo and getnameinfo are inverse functions of each other. They are network protocol agnostic, and support both IPv4 and IPv6. It is the recommended interface for name resolution in building protocol independent applications and for transitioning legacy IPv4 code to the IPv6 Internet.
Internally, the functions perform resolutions using the Domain Name System (DNS) by calling other, lower level functions, such as gethostbyname().
![]()
On February 16 2016 a security bug was announced in the glibc implementation of getaddrinfo(), using a buffer overflow technique, that may allow execution of arbitrary code by the attacker.[1]
struct addrinfo[edit]
The C data structure used to represent addresses and hostnames within the networking API is the following:
In some older systems the type of ai_addrlen is size_t instead of socklen_t. Most socket functions, such as accept() and getpeername(), require the parameter to have type socklen_t * and programmers often pass the address to the ai_addrlen element of the addrinfo structure. If the types are incompatible, e.g., on a 64-bit Solaris 9 system where size_t is 8 bytes and socklen_t is 4 bytes, then run-time errors may result.
The structure contains structures ai_family and sockaddr with its own sa_family field. These are set to the same value when the structure is created with function getaddrinfo in some implementations.
getaddrinfo()[edit]
getaddrinfo() converts human-readable text strings representing hostnames or IP addresses into a dynamically allocatedlinked list of struct addrinfo structures.The function prototypes for these functions are specified as follows:
Although implementations vary among platforms, the function first attempts to obtain a port number usually by branching on service. If the string value is a number, it converts it to an integer and calls htons(). If it is a service name, such as www, the service is lookup with getservbyname(), using the protocol derived from hints->ai_socktype as the second parameter to that function. Then, if hostname is given (not NULL), a call to gethostbyname() resolves it, or otherwise the address 0.0.0.0 is used, if hints->ai_flags is set to AI_PASSIVE, and 127.0.0.1 otherwise. It allocated a new addrinfo structure filled with the appropriate sockaddr_in in one of these conditions and also adds the port retrieved at the beginning to it. Canon mx860 user manual. Finally, the **res parameter is dereferenced to make it point to a newly allocated addrinfo structure.[4] In some implementations, such as the Unix version for Mac OS, the hints->ai_protocol overrides the hints->ai_socktype value while in others it is the opposite, so both need to be defined with equivalent values for the code to be work across multiple platforms.
getnameinfo()[edit]
getnameinfo() converts the internal binary representation of an IP address in the form of a struct sockaddr pointer into text strings consisting of the hostname or, if the address cannot be resolved into a name, a textual IP address representation, as well as the service port name or number. The function prototype is specified as follows:
freeaddrinfo()[edit]
This function frees the memory allocated by the getaddrinfo() function. As the result of the latter is a linked list of addrinfo structures, freeaddrinfo() loops through the list and frees each one in turn.
Example[edit]
The following example uses getaddrinfo() to resolve the domain name www.example.com into its list of addresses and then calls getnameinfo() on each result to return the canonical name for the address. In general, this produces the original hostname, unless the particular address has multiple names, in which case the canonical name is returned. In this example, the domain name is printed three times, once for each of the three results obtained.
