SERVICE_DESCRIPTIONW structure (winsvc.h)
Contains a service description.
Syntax
typedef struct _SERVICE_DESCRIPTIONW {
LPWSTR lpDescription;
} SERVICE_DESCRIPTIONW, *LPSERVICE_DESCRIPTIONW;
Members
lpDescription
The description of the service. If this member is NULL, the description remains unchanged. If this value is an empty string (""), the current description is deleted.
The service description must not exceed the size of a registry value of type REG_SZ.
This member can specify a localized string using the following format:
@[path]dllname,-strID
The string with identifier strID is loaded from dllname; the path is optional. For more information, see RegLoadMUIString.
Windows Server 2003 and Windows XP: Localized strings are not supported until Windows Vista.
Remarks
A description of NULL indicates no service description exists. The service description is NULL when the service is created.
The description is simply a comment that explains the purpose of the service. For example, for the DHCP service, you could use the description "Provides internet addresses for computer on your network."
You can set the description using the ChangeServiceConfig2 function. You can retrieve the description using the QueryServiceConfig2 function. The description is also displayed by the Services snap-in.
Examples
For an example, see Changing a Service's Configuration or Querying a Service's Configuration.
Note
The winsvc.h header defines SERVICE_DESCRIPTION as an alias that 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 is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
