How do I determine if an entry is a multi-assign?

LIBS: could be
Workbench:Libs
Workbench:MUI/Libs

bin: could be
Programming:SDK/local/C
Programming:SDK/C


BOOL

GetAssigns(VOID)

{

    BOOL                            Success=TRUE;

    struct Node                        *node;

    struct List                        *ADOList;



    struct DevProc                    *dp=NULL;



    if ((ADOList=IDOS->AllocDosObjectTags(DOS_VOLUMELIST,

        ADO_Type,                                LDF_ASSIGNS,

        ADO_AddColon,                            TRUE,

    TAG_END)))

    {

        for(node=IExec->GetHead(ADOList); node; node=IExec->GetSucc(node))

        {

            if ((dp=IDOS->GetDeviceProcFlags(node->ln_Name,0,LDF_ALL)))

            {

                if (dp->dvp_Flags & DVPB_MULTIASSIGN)

                {

                    IDOS->Printf("MultiAssign: %s\n",node->ln_Name);

                }



                IDOS->FreeDeviceProc(dp);

            }





            if (!(AssignsNode=(struct AssignsNode *)SAK_CreateGenericListNode(sizeof(struct AssignsNode),(STRPTR)"")))

            {

                SAK_EasyRequest(Objects[OID_WINDOW],MainWindow,RequesterTitle,REQIMAGE_WARNING,0,SAK_LocaleString(MSG_COULD_NOT_CREATE_EXEC_LIST_NODE),SAK_LocaleString(MSG_CONTINUE));

                Success=FALSE;

                break;

            }

            SAK_AddGenericListNode(MasterAssignsList,(struct Node *)AssignsNode,GLIST_BOTTOM);



            IUtility->SNPrintf(AssignsNode->Name,128,"%s",node->ln_Name);

            IUtility->SNPrintf(AssignsNode->UserData,128,"[Ass]%s",AssignsNode->Name);

        }



        IDOS->FreeDosObject(DOS_VOLUMELIST,ADOList);

    }



    return(Success);

}

Once I determine if it is a multi-assign, how do I get the list of paths for it?

The Asl file requester, Volumes, show multi-assigns in bold. When click on it, a new window opens with the items.

if (dp->dvp_Flags & DVPB_ASSIGNMENT)

gives me the multi-assign entries. Weird.

But now how do I get their items?

                            {

                                IDOS->Printf("MultiAssign: %s -> %s\n",node->ln_Name,Misc1Buffer);

                                error=0;

                            }

                            else

                                error=IDOS->IoErr();



                            if (error != 0)

                                break;



                        }

                    } while (dp2 && (dp2->dvp_Flags & DVPF_MULTIASSIGN));



                    IDOS->SetFileSysPort(filesystemtask);

                    if (dp2)

                    {

                        IDOS->FreeDeviceProc(dp2);

                        dp2=NULL;

                    }

                }

            }

        }



        if (dp)

            IDOS->FreeDeviceProc(dp);



        IDOS->FreeDosObject(DOS_VOLUMELIST,ADOList);

    }



    return(Success);

}

Are the
filesystemtask = IDOS->GetFileSysPort();
and
IDOS->SetFileSysPort(dp2->dvp_Port);
and
IDOS->SetFileSysPort(filesystemtask);
necessary? It works without them.

They are necessary because dp2->dvp_Lock can be ZERO if the assign is on the filesystem root.

If you didn't have these statements you would always get the SYS: partition from IDOS->NameFromLock() for such assigns.
