SERVICE_TYPE_VALUE_ABSW structure

-description

The SERVICE_TYPE_VALUE_ABS structure contains information about a network-service type value. This information may be specific to a namespace.

-struct-fields

-field dwNameSpace

Type: DWORD

A namespace, or a set of default namespaces, for which the network service type value is intended. Namespace providers will look only at values intended for their namespace.

Use one of the following constants to specify a namespace:

Value	Meaning
NS_DEFAULT	A set of default namespaces. The function queries each namespace within this set. The set of default namespaces typically includes all the namespaces installed on the system. System administrators, however, can exclude particular namespaces 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 operating systems register their computer names with NetBIOS. This namespace 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 namespace 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.

-field dwValueType

Type: DWORD

The type of the value data. Specify one of the following types:

Value	Meaning
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.

-field dwValueSize

Type: DWORD

The size, in bytes, of the value pointed to by the lpValue member. In the case of REG_SZ and REG_MULTI_SZ string data, the terminating characters are counted as part of the size.

-field lpValueName

Type: LPTSTR

A pointer to a NULL-terminated string that is the name of the value. This name is specific to a namespace.

Several commonly used value name strings are associated with defined constants. These name strings include the following.

Constant	Meaning
SERVICE_TYPE_VALUE_SAPID	"SapId"
SERVICE_TYPE_VALUE_CONN	"ConnectionOriented"
SERVICE_TYPE_VALUE_TCPPORT	"TcpPort"
SERVICE_TYPE_VALUE_UDPPORT	"UdpPort"

-field lpValue

Type: PVOID

A pointer to the value data.

-remarks

When you use the SetService function to add a network service type to a namespace, a SERVICE_TYPE_INFO_ABS structure is passed as the ServiceSpecificInfo BLOB member of a SERVICE_INFO structure. Although the ServiceSpecificInfo member generally should not contain pointers, an exception is made in the case of the SERVICE_TYPE_INFO_ABS and SERVICE_TYPE_VALUE_ABS structures.

Note

The nspapi.h header defines SERVICE_TYPE_VALUE_ABS as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
