Re: [Boost-users] boost::filesystem directory_iterator: how to get the last file of a directory ?

Zitat von "Vial, Florent" :

Hi boost-users,

I am using a recursvive function for iterating over a starting path. When i finally arrive in a directory that contains no subdirectory (what i call a "final" directory), i want to retrieve the first and the last file of this directory.

define "first" and "last". directory iterators are single-pass input iterators, meaning that they represent no particular order. if you iterate over the same directory 2 times, you might retrieve the entries in a different order. you could e.g. copy the entries to a std::vector using std::copy and then sort them, choose first and last, etc.
