HP System Dictionary XL Intrinsics

SDGetEntList 

Retrieve all entities of the specified entity type which are accessible
by the current scope.

Syntax 

     SDGetEntList (Dcb,EntityType,AccessSet,RetrievalID,Entity,Status)

Parameters 

Dcb                       Required input; type = DcbType 
                          This parameter passes information about the
                          dictionary to this intrinsic.  It is
                          initialized by the SDOpen intrinsic.

EntityType                Required input; type = NameOrNumberType 
                          This parameter specifies the entity type of the
                          entities to be retrieved.

AccessSet                 Required input by value; type = 4 byte Integer 
                          This parameter specifies the set of entities to
                          return.  This set may include some or all of
                          the entities of the specified type in the
                          dictionary, and is decoded as follows:

                          Note :  Bit 0 is the rightmost bit.

                          Bit 0         When set, specifies retrieval of
                                        all entities owned by the current
                                        scope.

                          Bit 1         When set, specifies retrieval of
                                        all entities accessible by the
                                        scope through an entity/scope
                                        association.

                          Bit 2         When set, specifies retrieval of
                                        all entities which are public,
                                        and not owned by or associated to
                                        the current scope.

                                        Note:  When this bit is set, and
                                        if the current scope is the DA
                                        scope, then this intrinsic will
                                        return all entities not owned by
                                        the DA scope.

                          Bits 3-31     Set to zero

RetrievalID               Required input; Output; type = RetrievalIDType 
                          This parameter is used internally to pass
                          information between multiple calls of this
                          intrinsic, to retrieve all the entities of the
                          specified entity type and access set in the
                          dictionary.

                          To find the first entity, initialize the first
                          four bytes of this parameter to a binary zero.
                          To find additional entities, call this
                          intrinsic once for each entity to be returned.

Entity                    Output; type = NameType 
                          This parameter returns the name of an entity of
                          the specified entity type for each successful
                          call of this intrinsic.

Status                    Output; type = StatusType 
                          This parameter contains information indicating
                          the success or failure of the intrinsic call.
                          This information is detailed in Table Table
                          3-1, located in Chapter 3 of this manual.

                          If this intrinsic is successful, the Status 
                          parameter contains the following information,
                          in addition to the description contained in
                          Table Table 3-1.
