; <14> 5/10/92 KSM Patches don<6F>t belong in this file.
; <13> 3/27/92 DC KSM - added InsertIntlResMenu
; <12> 1/20/92 PN Adding condition for ROM build
; <11> 8/22/91 KSM DCC,#Bruges: Added utility routine InsertFontResMenu for Finder.
; <10> 3/29/91 JSM dba, #85831: Set MenuBarGlobalInvalidBit in DrawMBARString.
; <9> 3/26/91 dba gbm: handle system menus correctly
; <8> 3/4/91 dba dty: get rid of SysVers conditionals
; <7> 12/3/90 RLC <ksm> Fix GetMenuTitleRect to return noErr.
; <6> 7/23/90 dba get rid of CallMBarProc, since this is now linked with
; MenuMgr.a, which has CallMBarProc in it
; <5> 6/8/90 KSM Add new IsSystemMenu(menuID) call.
; <4> 6/5/90 KSM Return a reasonable OSErr result on success!
; <3> 5/14/90 KSM Factor out common sections of rect calls.
; <2> 5/14/90 KSM Rewrite it to: a) Be enabled (again) under System 7.0 b) Be a
; linked patch and use the new dispatcher macros c) Add new calls
; to the MBDF.
; <1.0> 6/1/89 KSM Menu manager trap dispatcher for all new calls.
;
; To Do:
; *** Make a common file for the utility routines used here to share with menu manager
; *** Is it OK that D2 gets trashed calling GetMenuTitleRect from "C" (Pascal is OK)?

MACRO
CallMBDFWithRectMsgSwappingD0First
; It was more expensive to:
; 1) fix up the stack on the GetMenuTitleRect call to look like the other rect calls
; 2) then call the common rect code
; than it was to have 2 copies of the code contained in this macro,
; so it is here in this macro and referenced (expanded) ONLY twice.
SWAP D0 ; Move param1 (6 B.O.) to high word
MOVE.W #MBDFRectCall, D0 ; set up for rect info message
MOVE.L 4(SP), D1 ; put rect ptr in D1 for CallMBarProc
IMPORT CallMBarProc
JSR CallMBarProc ; Go do it.

; GetIndex
; GetIndex is a utility routine that returns an index into the menuList given a
; menuId. The menuId is passed in D1 while the index is returned in D0. If the
; menuId can't be found, D0 will return a zero. A0, A1 and D2 are trashed.
; The Z-flag can be used to determine if one was found. As a special bonus, on
; exit A0 points to the menu, if a menu was found.
GETINDEX PROC ENTRY
TST D1 ; is index 0?
BEQ.S NOINDEX ; if so, return 0
IMPORT GetA1List
JSR GetA1List ; get menuList into A1
MOVE LASTMENU(A1),D2 ; get # of menus
BEQ.S NOINDEX ; if none, say we can't find it
; here is the search loop. Get the next handle, and check the menuID
GILOOP MOVE.L MENUOH(A1,D2),D0 ; get the handle
MOVE.L D0,A0 ; get handle in A-reg
MOVE.L (A0),A0 ; handle -> pointer
CMP MENUID(A0),D1 ; is this the one?
BEQ.S GOTINDEX ; if they match, we're done

NEXTINDEX SUBQ #6,D2 ; bump to next entry
BNE.S GILOOP ; loop if there's more to do
; we couldn't find it so return zero in D0
NOINDEX MOVEQ #0,D2 ; return 0
