NAPI_DOMAIN_DESCRIPTION_BLOB Structure
The NAPI_DOMAIN_DESCRIPTION_BLOB structure describes a domain handled by a namespace provider for the NS_EMAIL namespace.
Syntax
typedef struct _NAPI_DOMAIN_DESCRIPTION_BLOB {
DWORD AuthLevel;
DWORD cchDomainName;
DWORD OffsetNextDomainDescription;
DWORD OffsetThisDomainName;
} NAPI_DOMAIN_DESCRIPTION_BLOB, *PNAPI_DOMAIN_DESCRIPTION_BLOB;
Mitglieder
AuthLevel
The authority level of the namespace provider for this domain. This member can be one of the values from the NAPI_PROVIDER_LEVEL enumeration type defined in the Nsemail.h header file.cchDomainName
The length, in Unicode characters, of the Unicode string that contains the domain name represented by the OffsetThisDomainName member. The NULL terminator is not counted when calculating the length.OffsetNextDomainDescription
The offset, in bytes, to the next NAPI_DOMAIN_DESCRIPTION_BLOB structure in the NAPI_PROVIDER_INSTALLATION_BLOB structure.OffsetThisDomainName
The offset, in bytes, to a Unicode string that contains a domain name handled by this namespace provider for the NS_EMAIL namespace. The domain name must be at least cchDomainName Unicode characters in length. NULL-termination of the Unicode string that contains the domain name is recommended, but not required. This offset must be aligned on a minimum of a two-byte boundary.
Hinweise
This structure is supported on Windows Vista and later.
The NAPI_DOMAIN_DESCRIPTION_BLOB structure describes a domain handled by a namespace provider for the NS_EMAIL namespace. A typical domain name represented by the OffsetThisDomainName member in this structure might be msn.com or yahoo.com.
Each namespace provider registered in the NS_EMAIL namespace can support multiple domains. The list of supported domains is specified in the provider registration blob as a list of NAPI_DOMAIN_DESCRIPTION_BLOB structures. Each supported domain specification contains a NAPI_PROVIDER_LEVEL value in the AuthLevel member of the NAPI_DOMAIN_DESCRIPTION_BLOB that describes the type of support provided by the provider for that domain.
The NAPI_DOMAIN_DESCRIPTION_BLOB structure is a member of the NAPI_PROVIDER_INSTALLATION_BLOB structure used to describe and register a NS_EMAIL namespace provider. There may be multiple NAPI_DOMAIN_DESCRIPTION_BLOB structures in the NAPI_PROVIDER_INSTALLATION_BLOB structure for an NS_EMAIL namespace provider.
The WSCInstallNameSpaceEx and WSCInstallNameSpaceEx32 functions are used to install a namespace provider for the NS_EMAIL namespace using a NAPI_PROVIDER_INSTALLATION_BLOB structure.
The WSAEnumNameSpaceProvidersEx and WSCEnumNameSpaceProvidersEx32 functions are used to enumerate all namespace providers (including NS_EMAIL namespace providers) and to retrieve the NAPI_PROVIDER_INSTALLATION_BLOB structure for a provider if the provider registered a blob upon installation.
