DLL Export Name

[guga]

There is another alternative and that is to use ordinals instead of names. I rarely ever use it but it does work and it appears to be a Microsoft technique to make tracking the exports more obscure, mainly against hacking.

Hi Steve and Jochen.

Yes, ordinal numbers are a alternative. RosAsm allows them to be used too. The problem is that, i would like to make things a bit simpler, like a check for forbidden chars when the user writes a call to a api function.

For what i read on the comments (nidud,Aw etc) there are some invalid chars that can be used for such a thing, but the compilation speed maybe a bit affected. So, perhaps, i´ll be forced to end simply allowing the user to write whatever he wants as it is already. So, when the user types a invalid api function the proper message will show up. (Since the verification of that api is done by loadlibrary etc, rosasm uses it´s return value to show the proper message).

I´m thinking in what could be better to do (If i use some of the forbidden chars or not). I just faced another problem regarding the LoadLibrary api concerning a deadlock i found in one dll from ffmpeg. I opened another thread for that specific problem. I´m quite sure it is a windows10 bug in LoadLibraryExW function, but, i posted there to try to find a workaround for that.

Guga,

Just do a lookup table with the allowable characters and reject the rest. Table below is numbers, upper and lower case characters for a US character set.

  db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
  db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
  db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
  db 1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0
  db 0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
  db 1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0
  db 0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
  db 1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0
  db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
  db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
