deleting a boost::filesystem::path object

[Daz]

Hi Everyone.

I am sturggling trying to find out a way in which I can delete a 'path'
object. I may not need to delete it, however, I need to overwrite it.
The function I am trying to code, converts a string into a 'path'
object, then checks to see if it exists. If it doesn't exist, the path
object needs to be reused and the new path string put into it (not
appended to it).

If anyone could help, or point out where I can find this information,
it would be very much appreciated. I have tried looking on boost.org,
but get lost in all the jargon and can't seem to find what I am looking
for.

Thanks in advance.

You might get much better results on the boost-users mailing list. It's
worth subbing to, at least until you get over the learning curve, and you
can lurk at news:news.gmane.org .

I will do just that. Thanks for the advice :)

Ok, I think I really am more stupid than I had originally suspected. I
am quite new to news groups, and I seriously don't understand how to
subscribe to the group, if I need software to view it, and how to
compile it on windows if it is needed. The only thing I can see for me
to do, is fill in a form, which looks as though it will create a new
group, which I don't think I want to do, or do I?

It doesn't look like anything I have ever seen before, and I have read
the FAQs which are very helpful, if I were to start a new group... :(

Sorry for being stupid, but thanks for your help. I will see if I can
figure it out.

path_object = boost::filesystem::path(new_path_string);

It's a mailing list. It's great for the full-timers, and sucks for
part-timers (quite the reverse of USENET). Fill out the form on their web
site, put your addy in, and you are there.

(And our newsgroup here is probably useful for _light_ Boost stuff...)

Excellent! I was just worried that I might have been needlessly
creating a new group that I had no intention of maintaining.

Thanks again Phlip. Both for your time, and your patience :)

It's very much appreciated.

Aaah, yes! I seem to remember reading about this in a tutorial
somewhere on c++ classes. I don't know why I didn't think of it, I
tried virtually everything else!

Thanks for the help Markus, much appreciated!

(namespace fs = boost::filesystem;)

Note however that fs::path() does not understand native path formats by
default, you must give it fs::native:

fs::path p("c:\\file", fs::native);

If you don't, it'll throw.
