Fast GetProcAddress

[db90h]

Cool ;). I figured I was missing something.

The 'CMOVA' confused me .. it is an instruction I had never used before ;). You have taught me something new today.

Sounds like you've got it all finished up now ;). Congrats on a cool implementation.

Thanks,

striker,

So you want _all_ exports from the module in one call?

db90h,

thanks, your code seems interesting, and the hint stuff is something i haven't heard of before.

x86asm,

Thanks for testing it.
Did the program crash immediatily when you executed it? Or did it crash after you pushed the benchmark button (if so, what was the library and proc name you searched?)?
The program is quite small, could you by any change step it trough with debugger? I suspect it crashes on the SetDlgItemTextA after getting the cpu vendor name with cpuid, the name is probably not null terminated..

It crashed immediately after I ran it, I will debug it and let you know where it goes wrong! :D

I have updated the library with the new function: http://personal.inet.fi/atk/partsu/GetProcLib.zip.

It is called GetProcOffsetEx, and it has an extra third parameter that accepts the hint. It's very fast when the hint is correct, and is still faster than GetProcAddress if the hint is wrong.. It's not much slower than the original GetProcOffset even the hint would be wrong, but i want to keep the original intact. If you don't need hints anywhere use the original version, and vice versa, but don't include both on the same project, as the functions are over 300bytes. :eek

invoke GetProcOffsetEx, hModule, szFunction, 06Bh

the SetDlgItemText worked perfectly, no error, after extracting my CPUID string and passing it to the function, it worked perfectly! no error! I found you error, you didnt save EBX, ESI or EDI after using it, you must! Because after calling your function, the API makes a reference using EBX without reloading it.

oops, the first cpuid instruction messes the ebx.. :red

New upload in the website.

+ plus, i also added the new function to the speed test..

YES.  :)

Hi,
    Any possiblilty of adding this to the MASM32 Library?

I certainly think that this would be a very useful addition to the masm32 distribution.  This is a very professional work and I am glad that you decided to repost it.

BTW:  I like the idea of doing a second search without the hint if the first one fails.

I can make a version without my macros, if hutch likes this to be added in the MASM32 library..

[pbrennick]

I think your macros would be a useful addition to the distribution, also.  You do very nice work.
