[boost.filesystem] remove issue
Hi:
I am using the following code with boost.filesystem:
size_t origsize = strlen(argv[0]) + 1;
size_t convertedChars = 0;
wchar_t wcstring[1024];
mbstowcs_s(&convertedChars, wcstring, origsize, argv[0],
strlen(argv[0]));
boost::filesystem::wpath path(wcstring);
path.filename() =L"compilation date.txt";
if (boost::filesystem::exists(path))
// boost::filesystem::remove(path);
I have defined:
#define BOOST_FILESYSTEM_NO_DEPRECATED
The line that causes probles is:
// boost::filesystem::remove(path);
Anyone got any ideas why this line causes a window error report to be
generated.
For reference I'm including:
#include
Hi!
probably you are trying to remove a directory? If so try using remove_all
instead.

Hi:
I don't think i am, I was under the impression that argv[0] gave me the
full executable path. If not, how do I obtain this.
Cheers
Sean.

Oh, sorry, my fault. But in that case you are trying to do smth very strange :) Take a look at the signature of path::filename. It returns a copy of the filename part. You just assign a new value to the temporary string. And than your app tries to delete the executable itself, which is locked by the running process. That's why you get an error. Your intention probably was: path.remove_filename() /= L"compilation date.txt"; if (boost::filesystem::exists(path)) boost::filesystem::remove(path); //should work Regards, Ovanes
