DnsServiceDeRegister function (windns.h)

Used to remove a registered service.

Syntax

DWORD DnsServiceDeRegister(
  PDNS_SERVICE_REGISTER_REQUEST pRequest,
  PDNS_SERVICE_CANCEL           pCancel
);

Parameters

pRequest

A pointer to the DNS_SERVICE_REGISTER_REQUEST structure that was used to register the service.

pCancel

Must be nullptr.

Return value

If successful, returns DNS_REQUEST_PENDING; otherwise, returns the appropriate DNS-specific error code as defined in Winerror.h. For extended error information, call GetLastError.

Remarks

This function is asynchronous. The callback will be invoked when the deregistration is completed, with a copy of the DNS_SERVICE_INSTANCE structure that was passed to DnsServiceRegister when the service was registered.
