Problem with "get file size" function.

Hi there,all!!!

I’ve faced the problem I can not solve. I use filter driver, but
in some application (wordpad forWin2K) inside the IRP_MJ_WRITE routine
I can not work with the file (for example, I can not get the file’s size)
before I call IoCallDriver, only after. I use for this function from
the Filemon(by Russinovich). What is wrong? What should I do?

So, what is the actual problem ? What status code do you get when you query
the file size ?

Hello Bartjan,

This function always return ZERO status code, but return ZERO file
size before I call IoCallDriver and new file size after. But I need
before!!! That is the problem!!!
