What should I do in multithreading if I change from x32 to x64 in VSF

hi
What should I do in multithreading if I change from x32 to x64 in Visual studio Fortran. I've tried a simple multithread test program under win32 platform and it runs well. However, it cannot pass the build process if I change the configuration to X64 platform. I will appreciate if anybody could give some help, thanks

here is my test code:

use IFMT
external threadfunc
PARAMETER(mTHREAD=2)
common /thread/A(2,10000)

integer(4) para(mThread)
integer hthread(mthread),idthread(mthread),hticketmutex
logical(4) waitall
integer(4) nresult,nwaitresult,nticket
common /ticket/nticket
common/mutex/hticketmutex

NTICKET=1

HTICKETMUTEX=CREATEMUTEX(0,.FALSE.,0)
WAITALL=.TRUE.
DO I=1,mTHREAD
para(i)=i
HTHREAD(I)=CREATETHREAD(0,0,THREADFUNC,loc(para(i)),0,IDTHREAD(I))
END DO
NWAITRESULT=WAITFORMULTIPLEOBJECTS(mTHREAD,HTHREAD(1),WAITALL,
& WAIT_INFINITE)

LOU=CLOSEHANDLE(hTicketMutex)

DO IJ=1,mTHREAD
LOU=CLOSEHANDLE(HTHREAD(IJ))
IF(LOU.EQ.0) THEN
PRINT *,'FAIL TO CLOSE HANDLES HTHREAD'
STOP
END IF
END DO
DO I=1,4
WRITE(*,*) A(1,I),A(2,I)
END DO
PAUSE
STOP
END



integer(4) function threadfunc(arg)
use IFMT
PARAMETER(mTHREAD=2)

common /thread/A(2,10000)

integer(4) arg
integer hticketmutex
logical(4) waitall
integer(4) nresult,nwaitresult,nticket
common /ticket/nticket
common/mutex/hticketmutex

nwaitresult=waitforsingleobject(hticketmutex,WAIT_INFINITE)


K1=NTICKET

nticket=nticket+1

DO I=1,10000
A(K1,I)=I*K1
END DO

threadfunc = 0
end function

Error 1 error #6284: There is no matching specific function for this generic function reference. [CREATEMUTEX] C:\jiang\Multithread tests\mt\mtest.FOR 16
Error 2 error #6284: There is no matching specific function for this generic function reference. [CREATETHREAD] C:\jiang\Multithread tests\mt\mtest.FOR 20

these codes work well under 32bit configurartion. Does it mean I need to use some different functions (such as CREATEMUTEX, CREATETHREAD) or change the configuration in project properties under X64 platform?
thanks again

Please repost this in the Fortran for Windows forum.

Also, try changing the types for your handles to HANDLE as opposed to integer(4)
