How to get the absolute path when intercepting the open system call

[mingleichen]

Hello, your work is quite nice. It is very helpful to me.

I want to identify the absolute path of the file to redirect to the file that I expect to open, but now I meet a problem, how to get the absolute path of the file when intercepting the open system call. I tried to use PEEKUSER to get the file name parameter of the open system call, but what I got was a relative path. If you have any thoughts, I will be grateful for you to tell me.

Thanks.
