This structure is used by the getaddrinfofunction 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 getaddrinfofunction. 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_addrmember.

ai_canonname

Canonical name for the host.

ai_addr

Pointer to a sockaddrstructure.

ai_ next

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