NAME
   CSSM_Introduce - Identify an executable module (CDSA)

 SYNOPSIS
   # include <cssm.h>

        CSSM_RETURN CSSMAPI CSSM_Introduce
        (const CSSM_GUID *ModuleID,
        CSSM_KEY_HIERARCHY KeyHierarchy)

 LIBRARY
   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 PARAMETERS
   ModuleID (input)
           The CSSM_GUID of the calling library or other library that
           might call CDSA interfaces. The GUID is used to locate the
           signed manifest credentials of the named module to calculate
           module integrity information.

   KeyHierarchy (input)
           The CSSM_KEY_HIERARCHY option directing CSSM what embedded
           key to use when verifying integrity of the named module.

 DESCRIPTION
   The CSSM_Introduce() function identifies a dynamically loadable
   executable module (for example, DLL) to the CSSM framework. CSSM uses
   the ModuleID information to locate the signed manifest and library on
   the host platform.  The Module Directory Service (MDS) should be used
   to obtain the information. CSSM performs an integrity cross-check on
   the module identified by ModuleID and caches the result in an internal
   structure. The integrity cross-check uses the KeyHierarchy information
   to determine which classes of embedded public keys must serve as
   anchors when doing certificate path validation. If the export key
   hierarchy is specified, the set of export privileges contained in the
   manifest are retrieved from the manifest and saved with the integrity
   state information in the cache.  Privileges granted to a module are
   accepted only if the manifest sections containing the privilege set
   have been signed by a principal in the export key hierarchy class and
   that hash of the module binary is part of the hash of the privilege
   attributes.

   The CSSM_Introduce() can be called at any time after CSSM_Init(), by
   any module, on behalf of any module.

   Once a module is introduced into CSSM the load location of the module
   must not change. If the load location changes then the module must be
   reintroduced.  Once introduced, the module load location, integrity,
   and privilege information is held until CSSM_Terminate() is called or
   the process terminates. Initialization of internal data structures
   maintaining the table of introductions is performed when CSSM_Init()
   is called.

   If CSSM_Introduce() is called on behalf of another module, then the
   caller needs to make sure that the other module is loaded into the
   process address space. If the library is already loaded into process
   address space, but a reference to the library cannot be obtained, a
   different error is returned (CSSMERR_CSSM_LIB_REF_NOT_FOUND).

 RETURN VALUE
   A CSSM_RETURN value indicating success or specifying a particular
   error condition. The value CSSM_OK indicates success. All other
   values represent an error condition.

 ERRORS
   Errors are described in the CDSA technical standard.  See CDSA.

        CSSMERR_CSSM_INVALID_KEY_HIERARCHY
        CSSMERR_CSSM_LIB_REF_NOT_FOUND
