[Click] File operations in Click

[Jelena Mirkovic]

I've been trying to write a kernel module in Click that reads address  
info from a file, then manipulates (drops or forwards) packets for  
the specified addresses. I've had problems with using fopen -  
basically click-install informs me that fopen is unknown symbol even  
though I've included stdio.h in my file. I seem to remember Linux  
kernel has a problem manipulating files. Is there an easy way to open  
and read a file from a Click kernel module?

Thanks
