Hello,
I am trying to call the open function from within a kernel module.
After searching the web, I tried the following snippet:
mm_segment_t old_fs;
old_fs=get_fs();
set_fs(USER_DS);
fp=open('/etc/config.txt',O_RDONLY);
getLine(fp,line);
close(fp);
set_fs(old_fs);
For some reason, the open fails and returns -1. Any ideas on what I am
doing wrong? This is all really new to me.
thanks,
Brad
