Using stat() outside of main() - getting incorrect info

ptimothy (1)
For a project, I am use to write a programs that the user provides an inode number and the program returns all information on that file. (OS: Back Track 5 using VMplayer, C code)

I am using the sprintf and popen() function to find the file name based on the inode number. Then, I call a function called inodeData(char* file) and inside that function, I use stat() to gather the information on that file.

When I run the code, the file name is correct (based on the inode) but all the other information is not correct. Almost all examples I have found using stat() take in user input from the main, but I am not doing that in this program.

You're never actually calling stat()

Another, more subtle, error, is that your "file" contains an extra endline character (that's what fgets does), so even if you call stat(file, &sb);, it will fail.
