HTTP_SERVICE_CONFIG_IP_LISTEN_QUERY structure

The HTTP_SERVICE_CONFIG_IP_LISTEN_QUERY structure is used by HttpQueryServiceConfiguration to return a list of the Internet Protocol (IP) addresses to which the HTTP service binds.

Syntax


typedef struct _HTTP_SERVICE_CONFIG_IP_LISTEN_QUERY {
  ULONG            AddrCount;
  SOCKADDR_STORAGE AddrList[1];
} HTTP_SERVICE_CONFIG_IP_LISTEN_QUERY, *PHTTP_SERVICE_CONFIG_IP_LISTEN_QUERY;

Members

AddrCount

The number of address structures in the AddrList array.

AddrList

An array of SOCKADDR_STORAGE structures that contains IP addresses in either IPv4 or IPv6 form. To determine what form an address in the list has, cast it to a SOCKADDR and examine the sa_family element. If sa_family is equal to AF_INET, the address is in IPv4 form, or if it is equal to AF_INET6, the address is in IPv6 form.

Remarks

An IPv4 address may be expressed as a literal string of four dotted decimal numbers, each in the range 0-255, such as 192.168.197.113. IPv4 addresses are contained in sockaddr_in structures, declared in the Windows header file Winsock2.h as follows:

  struct sockaddr_in {
    short    sin_family;        /* == AF_INET */
    u_short  sin_port;          /* Transport-level port number */
    struct   in_addr sin_addr;  /* IPv4 address */
    char     sin_zero[8];
  };

The SOCKADDR_IN structure is exactly equivalent to sockaddr_in by typedef.

An IPv6 address can be expressed as a literal string enclosed in square brackets that contains hex numbers separated by colons; examples are: [::1] and [3ffe:ffff:6ECB:0101]. IPv6 addresses are contained in sockaddr_in6 structures, declared in the Windows header file WS2tcpip.h as follows:

  struct sockaddr_in6 {
    short    sin6_family;       /* == AF_INET6 */
    u_short  sin6_port;         /* Transport-level port number */
    u_long   sin6_flowinfo;     /* IPv6 flow information */
    IN6_ADDR sin6_addr;         /* IPv6 address */
    u_long   sin6_scope_id;     /* set of scope interfaces */
  };

The SOCKADDR_IN6 structure is exactly equivalent to sockaddr_in6 by typedef.
