[gem5-users] Re: How to redirect the fopen to open a different file instead of specifed filename in the program binary given as input to gem5 simulator in SE mode

Hi Gogineni,

If you REALLY CAN'T modify the app, I would then replace the file(s) your app 
opens with a symlink to the file you want to open.

And if you feel in a hacky mood, you can dive in src/sim/syscall_emul.hh and 
hardcode path override in openatFunc. Needless to say this is a terrible long 
term solution, but a fun exercise to get in touch with syscall emulation ;)
