addrinfo (Windows Embedded CE 6.0)

1/6/2010

This structure is used by the getaddrinfo function to hold host address information.

Syntax

struct addrinfo {
  int ai_flags;
  int ai_family;
  int ai_socktype;
  int ai_protocol;
  size_t ai_addrlen;
  char* ai_canonname;
  struct sockaddr* ai_addr;
  struct addrinfo* ai_next;
};

Members

• ai_flags
  Flags that indicate options used in the getaddrinfo function. See AI_PASSIVE, AI_CANONNAME, and AI_NUMERICHOST.

• ai_family
  Protocol family, such as PF_INET.

• ai_socktype
  Socket type, such as SOCK_RAW, SOCK_STREAM, or SOCK_DGRAM.

• ai_protocol
  Protocol, such as IPPROTO_TCP or IPPROTO_UDP. For protocols other than IPv4 and IPv6, set this value to zero.

• ai_addrlen
  Length of the ai_addr member.

• ai_canonname
  Canonical name for the host.

• ai_addr
  Pointer to a sockaddr structure.

• ai_ next
  Pointer to the next structure in a linked list. The last addrinfo structure of a linked list sets this value to NULL.
