Appending to boost::filesystem::path

Question

I have a certain boost::filesystem::path in hand and I\'d like to append a string (or path) to it.

boost::filesystem::path p(\"c:\\\\dir\");
p.appen         


        

Answer 1

If it's really just the file name extension you want to change then you are probably better off writing:

p.replace_extension(".foo");

for most other file path operations you can use the operators /= and / allowing to concatenate parts of a name. For instance

boost::filesystem::path p("c:\\dir");
p /= "subdir";

will refer to c:\dir\subdir.
