The WSANAMESPACE_INFOEX structure contains all registration information for a namespace provider.
Type: GUID
A unique GUID for this namespace provider.
Type: DWORD
The namespace supported by this provider.
Possible values for the dwNameSpace member are listed in the Winsock2.h include file. Several namespace providers are included with Windows Vista and later. Other namespace providers can be installed, so the following possible values are only those commonly available. Many other values are possible.
Type: BOOL
If TRUE, indicates that this namespace provider is active. If FALSE, the namespace provider is inactive and is not accessible for queries, even if the query specifically references this namespace provider.
Type: DWORD
The version number of the namespace provider.
Type: LPTSTR
A display string that identifies the namespace provider.
Type: BLOB
A provider-specific data blob associated with namespace entry.
The WSANAMESPACE_INFOEX structure is an enhanced version of the WSANAMESPACE_INFO structure that is used by the WSAEnumNameSpaceProvidersEx and the WSCEnumNameSpaceProvidersEx32 functions to return information on available namespace providers. The WSANAMESPACE_INFOEX structure contains the provider-specific data blob associated with the namespace entry passed in the lpProviderInfo parameter to the WSCInstallNameSpaceEx and WSCInstallNameSpaceEx32 functions.
Currently, the only namespace included with Windows that uses information in the ProviderSpecific member of the WSANAMESPACE_INFOEX structure are namespace providers for the NS_EMAIL namespace. The format of the ProviderSpecific member for an NS_EMAIL namespace provider is a NAPI_PROVIDER_INSTALLATION_BLOB structure.
When UNICODE or _UNICODE is defined, WSANAMESPACE_INFOEX is defined to WSANAMESPACE_INFOEXW, the Unicode version of this structure and the lpszIdentifier string member is defined to the LPWSTR data type.
When UNICODE or _UNICODE is not defined, WSANAMESPACE_INFOEX is defined to WSANAMESPACE_INFOEXA, the ANSI version of this structure and the lpszIdentifier string member is defined to the LPSTR data type.
The WSCEnumNameSpaceProvidersEx32 function is a Unicode only function and returns WSANAMESPACE_INFOEXW structures.
Note
The winsock2.h header defines WSANAMESPACE_INFOEX 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.
