Windows.Networking.ServiceDiscovery.Dnssd Namespace
Supports the registration and discovery of services that advertise themselves using DNS Service Discovery (DNS-SD).
Note
Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse.
Classes
| DnssdRegistrationResult |
Encapsulates detailed information about the result of an attempt to register a service instance using DNS-SD. Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
| DnssdServiceInstance |
Encapsulates an instance of a service that uses DNS Service Discovery (DNS-SD). Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
| DnssdServiceInstanceCollection |
A collection of DNS Service Discovery (DNS-SD) service instances. Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API. Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
| DnssdServiceWatcher |
Maintains a collection of available DNS Service Discovery (DNS-SD) service instances. Note DnssdServiceWatcher is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API. Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
Enums
| DnssdRegistrationStatus |
Values representing the status of a DNS-SD registration attempt. Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
| DnssdServiceWatcherStatus |
Values representing the status of a DnssdServiceWatcher. Note DnssdServiceWatcher is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API. Note Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse. |
Remarks
Server code uses the members of this namespace to advertise services available to clients on a local network, via DNS Service Discovery (DNS-SD). Client code uses the members of this namespace to identify services being offered via DNS-SD. The actual communication between client and server takes place over sockets, using ports and protocols advertised and discovered through DNS-SD.
DNS-SD is described in RFC 6763. For context and general information about DNS, see RFC 1034.
