Using it in conjunction with ; normal function declaration (with the new name) will solve an error ; caused by a long parameter list routine that exhausts page width. ; ; stdRET Func ; to return from Func routines (declared with stdPROC or ProcName.) ; ; stdENDP Func ; to declare the end of routine (declared with stdPROC or ProcName.) ; ; endMod Func ; to declare the end of module with an entry point at Func (declared ; with stdPROC or ProcName.) ; ; stdCall Func,ArgList ; to call to a routine--Func--with the arguments pushed on the stack ; ; MovAddr dest,Func,n ; to move the address of the routine--Func--into dest. ; ; Note that for the standard calling convention all the function names, ; Func, are automatically converted to Func@N where N is the number of ; bytes (decimal) in the argument list. ; ; History: ; Thu 15-Aug-1991 16:21:14 -by- Viroon Touranachun [viroont] ; Created ; ; John Vert (jvert) 3-Aug-1992 ; Stolen from GDI and modified for use in the kernel ; ;**************************************************************************** IFNDEF STD_CALL ;**************************************************************************** ; ; This section is used exclusively for C calling convention. ; ;**************************************************************************** PUBLICP macro Func,N public &Func endm EXTRNP macro Func,N,Thunk extrn &Func:NEAR endm LABELP macro Func,N &Func LABEL NEAR endm ProcName macro Name,Func,N &Name EQU <&Func> endm stdPROC macro Func,N,ArgList &Func proc &ArgList endm cPublicProc macro Func,N,ArgList align dword PUBLICP Func,N stdPROC Func,N,&ArgList endm cPublicFpo macro FpoLocals, FpoParams endm stdRET macro Func ret endm stdENDP macro Func &Func endp endm endMod macro Func end xxx&Func endm stdCall macro Func,ArgList Local Bytes RevPush <ArgList>,Bytes Bytes = Bytes*4 call &Func if Bytes GT 0 add esp,Bytes endif endm MovAddr macro dest,addr,n mov dest,offset FLAT:&addr endm ELSE ;**************************************************************************** ; ; This section is used exclusively for the standard calling convention. ; ;**************************************************************************** PUBLICP macro Func,N ifb <N> public &Func&@0 else PUBLICP2 Func,%(N*4) endif endm PUBLICP2 macro Func,N public &Func&@&N endm EXTRNP macro Func,N,Thunk ifb <N> IFNDEF &Func&@0 extrn &Func&@0:NEAR ENDIF else ifb <Thunk> EXTRNP2 Func,%(N*4) else EXTRNTHUNK Func,%(N*4) endif endif endm EXTRNP2 macro Func,N IFNDEF &Func&@&N extrn &Func&@&N:NEAR ENDIF endm EXTRNTHUNK macro Func,N IFNDEF __imp_&Func&@&N extrn __imp_&Func&@&N:DWORD ENDIF endm LABELP macro Func,N ifb <N> &Func&@0 LABEL NEAR else &Func&@&N LABEL NEAR endif endm ProcName macro Name,Func,N ifb <N> cByte&Func EQU 0 &Name EQU <&Func&@0> else cByte&Func EQU N &Name EQU <&Func&@&N> endif endm stdPROC macro Func,N,ArgList ProcName &Func,Func,%(N*4) &Func proc &ArgList endm cPublicProc macro Func,N,ArgList align dword PUBLICP Func,N ifb <N> stdPROC Func,0,<&ArgList> else stdPROC Func,N,<&ArgList> endif endm stdRET macro Func ret cByte&Func endm cPublicFpo macro FpoLocals, FpoParams .FPO ( FpoParams, FpoLocals, 0, 0, 0, 0 ) endm stdENDP macro Func &Func endp endm endMod macro Func end &Func endm stdCallCall macro Func,N IFDEF __imp_&Func&@&N call dword ptr [ __imp_&Func&@&N ] ELSE call &Func&@&N ENDIF endm stdCallThunk stdCall macro Func,ArgList Local Bytes RevPush <ArgList>,Bytes Bytes = Bytes*4 stdCallCall Func,%(Bytes) endm MovAddr macro dest,addr,n ComposeInst <mov >,dest,<,offset FLAT:>,addr,<@>,n endm ENDIF ;STD_CALL
