Members
dwNameSpace
Specifies the name space, or a set of default name spaces, for which the network service type value is intended. Name-space providers will look only at values intended for their name space.The following table shows the constants you use to specify a name space.
Value Name space NS_DEFAULT
A set of default name spaces. The function queries each name space within this set. The set of default name spaces typically includes all the name spaces installed on the system. System administrators, however, can exclude particular name spaces from the set. NS_DEFAULT is the value that most applications should use for dwNameSpace.
NS_DNS
The Domain Name System used in the Internet for host name resolution.
NS_NETBT
The NetBIOS over TCP/IP layer. All Windows NT® and Windows® 2000 systems register their computer names with NetBIOS. This name space is used to convert a computer name to an IP address that uses this registration. Note that NS_NETBT may access a WINS server to perform the resolution.
NS_SAP
The Netware Service Advertising Protocol. This may access the Netware bindery if appropriate. NS_SAP is a dynamic name space that allows registration of services.
NS_TCPIP_HOSTS
Lookup value in the <systemroot>\system32\drivers\etc\hosts file.
NS_TCPIP_LOCAL
Local TCP/IP name resolution mechanisms, including comparisons against the local host name and looks up host names and IP addresses in cache of host to IP address mappings.
dwValueType
Type of the value data. The following table shows the types you can specify.Value Description REG_BINARY
Binary data in any form.
REG_DWORD
A 32-bit number.
REG_MULTI_SZ
An array of null-terminated strings, terminated by two null characters.
REG_SZ
A null-terminated string.
- dwValueSize
Size of the value data, in bytes. In the case of REG_SZ and REG_MULTI_SZ string data, the terminating characters are counted as part of the size.
lpValueName
Pointer to a zero-terminated string that is the name of the value. This name is specific to a name space.Several commonly used value name strings are associated with defined constants. The following table shows the available name strings.
Constant Name string SERVICE_TYPE_VALUE_SAPID
"SapId"
SERVICE_TYPE_VALUE_CONN
"ConnectionOriented"
SERVICE_TYPE_VALUE_TCPPORT
"TcpPort"
SERVICE_TYPE_VALUE_UDPPORT
"UdpPort"
- lpValue
Pointer to the value data.
