I'm getting path to current directory with boost filesystem, then checking if the directory exists.
is_directory()
is ok, but exists()
fails on the same path, am I missing something?
Example code (boost 1.35):
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/path.hpp>
namespace fs = boost::filesystem;
// the path is full path /home/my/somedirectory
fs::path data_dir(fs::current_path());
fs::is_directory(data_dir) // true, directory exists
fs::exists(data_dir) // false
exists(status(data_dir)) // false
EDIT:
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/path.hpp>
namespace fs = boost::filesystem;
fs::path data_dir(fs::current_path());
// data_dir == "/home/myusername/proj/test"
if (fs::is_directory(data_dir)) // true - is directory
if (fs::is_directory(fs::status(data_dir))) // true - it is still a directory
Fun part:
if (fs::exists(fs::status(data_dir))) // true - directory exists
if (fs::exists( data_dir )) // true - directory exists
BUT:
if (!fs::exists(fs::status(data_dir))) // false - directory still exists
if (!fs::exists( data_dir )) // true - directory does not exists
The following is from the Boost source code:
inline bool is_directory( file_status f ) { return f.type() == directory_file; }
inline bool exists( file_status f ) { return f.type() != status_unknown && f.type() != file_not_found; }
As you can see, if is_directory
returns true then exists
must return true as well. Maybe the problem is elsewhere in your code - please post a minimal compilable example that shows the problem.
You may also want to try using the same file_status
object for both calls, to see if maybe the output status
was changing.
