Hi!
Why I obtain an error at program closing using this macro? There is no error if I allow winXP compatibility in exe properties.
CopiaObjeto macro tipo_de_objeto, ObjectDest, ObjectOrig
DbgText "CopiaObjeto macro"
;int 3
push esi
push edi
push ecx
pushfd
mov edi, &ObjectDest;[Dest]
cld
mov esi, &ObjectOrig
mov ecx , sizeof TPL_&tipo_de_objeto;[ln]
rep movsb
popfd
pop ecx
pop edi
pop esi
endm
Thanks in advance.
That code should work anywhere. What are the instructions "pushfd" "popfd" being used for when the data copy has nothing to do with processor flags ?
Thanks Hutch!
I put all the push and pop just in case ("cld" change direction flag). Only "esi" need to be preserved.
The extrange thing is that Xp compatibilty remove the issue, it's almost the same code you showed for 64bits.
What is "an error"? What do you see happen in the debugger after the int 3?
If rep it's not the problem then... I'm overwriting something necesary to dipose the objects! :icon_redface: And trying to destroy 2 times the same object result in a random jump (theory here).
I'm sure in ObjAsm there is an especific function, but it's a little hard to find :icon_eek:.
Hutch: Perhaps you can move the topic to ObjAsm, because (I think now) the issue is related to that (another option it's subforum "Beer abstinence consequences") :biggrin: .
Thanks very much.
