(const CSSM_GUID *ModuleGUID,
CSSM_SERVICE_MASK UsageMask,

LIBRARY
Module Directory Services library (cdsa$mds300_shr.exe)
PARAMETERS
| ModuleGUID (input) |
| | | A pointer to the CSSM_GUID structure containing
the Globally Unique ID of the add-in module. |
| UsageMask (input) |
| | | A bit mask specifying the module usage types used
to restrict the capabilities information returned by this function.
An input value of zero specifies all usages for the specified module. |
| SubserviceID (input) |
| | | A single subservice ID. Note that the operation
may already be limited by a service mask. If so, the subservice
ID applies to all service categories selected by the service mask. |
| USEERequest (input) |
| | | United States Export Exemption tag; should be set
to CSSM_USEE_NONE. |
| pModuleInfo (output) |
| | | A pointer to the module information. |
DESCRIPTION
This function gets a list of descriptive information from
the MDS registry for the add-in module identified by the ModuleGUID.
The information returned can include all of the capability information
for each of the subservices for each of the service types implemented
by the selected module. The request for information can be limited
to a particular set of services, as specified by the UsageMask.
The request may be further limited to one or all of the subservices
implemented in one or all of the service categories. The MDSUTIL_FreeModuleInfo
function must be called to deallocate memory containing the list.
RETURN VALUE
NULL — Error in retrieving information from the MDS
registry.
Not NULL — A pointer to a module info structure containing
a pointer to an array of zero or more service information structures.
Each structure contains type information identifying the service
description as representing certificate library services, data storage
library services, and so on. The service descriptions are sub-classed
into subservice descriptions that describe the attributes and capabilities
of a subservice.
ERRORS
Errors are described in the CDSA Technical Standard.
