* If the operating system does not provide a struct addrinfo, the
* following structure is used:
- *
+ *
* \code
* struct addrinfo {
* int ai_flags; // AI_PASSIVE, AI_CANONNAME
* struct addrinfo *ai_next; // next structure in linked list
* };
* \endcode
- *
- *
+ *
+ *
* hints is an optional pointer to a struct addrinfo. This structure can
* be used to provide hints concerning the type of socket that the caller
* supports or wishes to use. The caller can supply the following
* structure elements in *hints:
- *
+ *
* <ul>
* <li>ai_family:
* The protocol family that should be used. When ai_family is set
* to PF_UNSPEC, it means the caller will accept any protocol
* family supported by the operating system.</li>
- *
+ *
* <li>ai_socktype:
* denotes the type of socket -- SOCK_STREAM, SOCK_DGRAM or
* SOCK_RAW -- that is wanted. When ai_socktype is zero the caller
* will accept any socket type.</li>
- *
+ *
* <li>ai_protocol:
* indicates which transport protocol is wanted: IPPROTO_UDP or
* IPPROTO_TCP. If ai_protocol is zero the caller will accept any
* protocol.</li>
- *
+ *
* <li>ai_flags:
* Flag bits. If the AI_CANONNAME bit is set, a successful call to
* lwres_getaddrinfo() will return a null-terminated string
* address portion of the socket address structure will be set to
* INADDR_ANY for an IPv4 address or IN6ADDR_ANY_INIT for an IPv6
* address.<br /><br />
- *
+ *
* When ai_flags does not set the AI_PASSIVE bit, the returned
* socket address structure will be ready for use in a call to
* connect(2) for a connection-oriented protocol or connect(2),
* chosen. The IP address portion of the socket address structure
* will be set to the loopback address if hostname is a NULL
* pointer and AI_PASSIVE is not set in ai_flags.<br /><br />
- *
+ *
* If ai_flags is set to AI_NUMERICHOST it indicates that hostname
* should be treated as a numeric string defining an IPv4 or IPv6
* address and no name resolution should be attempted.
* </li></ul>
- *
+ *
* All other elements of the struct addrinfo passed via hints must be
* zero.
- *
+ *
* A hints of NULL is treated as if the caller provided a struct addrinfo
* initialized to zero with ai_familyset to PF_UNSPEC.
- *
+ *
* After a successful call to lwres_getaddrinfo(), *res is a pointer to a
* linked list of one or more addrinfo structures. Each struct addrinfo
* in this list cn be processed by following the ai_next pointer, until a
* corresponding arguments for a call to socket(2). For each addrinfo
* structure in the list, the ai_addr member points to a filled-in socket
* address structure of length ai_addrlen.
- *
+ *
* All of the information returned by lwres_getaddrinfo() is dynamically
* allocated: the addrinfo structures, and the socket address structures
* and canonical host name strings pointed to by the addrinfostructures.
* successful call to lwres_getaddrinfo() is released by
* lwres_freeaddrinfo(). ai is a pointer to a struct addrinfo created by
* a call to lwres_getaddrinfo().
- *
+ *
* \section lwresreturn RETURN VALUES
- *
+ *
* lwres_getaddrinfo() returns zero on success or one of the error codes
* listed in gai_strerror() if an error occurs. If both hostname and
* servname are NULL lwres_getaddrinfo() returns #EAI_NONAME.
