Hello again,
just wanted to leave a note, that today nobody can let me in to test this solution.. so these tests must be left for tomorrow 🙁
And yes, the memory consumption is jumping
from 48.868 MB to 48.528MB and so on.

I'll be back with the results tomorrow I hope

Well, it seems to me that the ~1MB of initial increase and tiny oscillation at the top is a bit nicer than the several hundred megabytes of oscillation with mass resetting of the search slots you'd normally get.

The general idea might be a useful improvement for DOSBox as a patch; where the search resources are immediately released for filespecs not containing wildcards. With the TSR, any program that performs an additional FindNext will get a "no more files" error, which is the expected and correct result; but DOSBox shows an "invalid search ID" error in its debug output because the search resources have been released. Shouldn't see any kind of error (even if harmless) for a normal FindFirst/FindNext sequence, so that little issue should be handled as part of a patch.

yeah, such a patch would be possible, although it's more an improvement than a bugfix.
Still I don't mind having it in dosbox.

maybe I could then somehow make an .iso from my little program, but then I would need 'write' access to mounted iso.. But... I think there is no such possibility?

As per the readme (which you read, right?), imgmount doesn't only work with isos - it works with read-write hard drive images and floppy images as well. Hard drive images can be made with imgmake, from HAL9000's DOSBox Megabuild; floppy images are easily manipulated with Virtual Floppy Drive and would be a better bet if this program is small enough for a floppy. Either option is probably preferable to recompiling DOSBox. 😉

Well I must say I have good news 😀
Yesterday I left the pc life, and today I went to check how is it going, memory is ok, doing normal 😀 So I think the problem is solved!
ripsaw8080, I can't describe how thankful I am! I must say that without DosBox and you, I would not have managed to deal with this problem!

Thank you very much!

Hello Jorpho! after your post, I've re-read the readme one more, and now I understand that I probably miss-understood something.. maybe because I was reading it at 5 A.M... not sure 😀 But It'll be a good lesson for me in future!

Thank you everyone!

Maybe something like this gets the job done .....

might even be able to check only for '?'
if we translate * to ??? in findfirst. I recall some version of DOS do that in the DTA.

Hello.

Since this topic bumped up, I decided to reply. the last attached 'program' from ripsaw8080 really works. A month passed, computer has not been powered off - still no problem at all, no single memory leak or smth like that 😀

Thank you very much ripsaw8080!

You saved my life!

Good luck with running a security-related dos application in a games-targetting emulator!
