[LC++]Unresolved symbol when loading module

[Krishna Monian]

I basically need the working directory of the process
that calls particular system calls(open for example)
that I am rerouting. 

I have seen this being done in code earlier. However I
am not too sure how exactly it was done.

How else can I get the working directory of the
calling process? I do not have a process struct that
comes in when the call is made. I only have the
filename, flags and mode.

Thanks
