DnsSetApplicationSettings function (windns.h)

Configures per-application DNS settings. This includes the ability to set per-application DNS servers either as fallback to the system configured servers, or exclusively.

Syntax

DWORD DnsSetApplicationSettings(
  DWORD                          cServers,
  const DNS_CUSTOM_SERVER        *pServers,
  const DNS_APPLICATION_SETTINGS *pSettings
);

Parameters

cServers

Type: _In_ DWORD

The number of custom DNS servers present in the pServers parameter.

pServers

Type: _In_reads_(cServers) DNS_CUSTOM_SERVER*

An array of DNS_CUSTOM_SERVER that contains cServers elements. If cServers is 0, then this must be NULL.

pSettings

Type: _In_opt_ DNS_APPLICATION_SETTINGS*

A pointer to a DNS_APPLICATION_SETTINGS object describing additional settings for custom DNS servers.

If this is NULL, then the custom DNS servers passed to the API will be used as fallback to the system-configured ones.

If this points to a DNS_APPLICATION_SETTINGS object that has the DNS_APP_SETTINGS_EXCLUSIVE_SERVERS flag set in its Flags member, then it means use the custom DNS servers exclusively.

Return value

A DWORD containing ERROR_SUCCESS on success, or an error code on failure.
