Suppose the following directory:
C:\export
As a command line argument in one of my applications, I get an absolute path to a file. I want to check if this file exists at some nested level inside of C:\export. Suppose the file passed in is:
C:\export\blah\myfile.txt
I would like to be able to call some sort of function that returns 'true' if the file (myfile.txt) exists within the directory tree rooted at C:\export.
Now suppose this next file:
C:\work\anotherfile.txt
The function in question would return 'false' here since anotherfile.txt does not exist inside of c:\export.
Something like the following would work for me.
is_file_within_directory_tree( "C:\export", "C:\work\anotherfile.txt" ); // returns false is_file_within_directory_tree( "C:\export", "C:\export\blah\myfile.txt" ); // returns true
Is there an easy way to do this with Boost.Filesystem?
Ooops, meant to post this to the users list. Since it's here already I won't cross post it there. Sorry, Michael Marcin
