Otherwise, if opts & copy_options::create_symlinks, then create_symlink(to, from). If opts & copy_options::directories_only, then do nothing. Otherwise, if !exists(t)& options & copy_options::copy_symlinks, then copy_symlink(from, to, opts).
If options & copy_options::skip_symlinks, then do nothing. If !exists(f) || equivalent(f, t) || is_other(f) || is_other(t) || is_directory(f)& is_regular_file(t), they then report an error (and do nothing else). If opts & (copy_options::create_symlinks | copy_options::skip_symlinks), by calling symlink_status The functions first determine the file_status values f for from and t for to: Skip_existing, overwrite_existing, or update_existingĭirectories_only, create_symlinks, or create_hard_links
The functions all possibly copy or link one or more files at from to to under control of opts, which is taken as copy_options::none for the overloads with no opts parameter.

(dot is the current directory established by previous path components) is removed.Įvery pair of path components X/. The functions all form an absolute pathname pabs = absolute(pval, base) (or pabs = absolute(pval) for the overload with no base parameter), then reduce it to a canonical form in the following sequence of steps:Įvery path component X for which is_symlink(X) is true is replaced by read_symlink(X).Įvery path component. Path canonical(const path& pval, const path& base, error_code& ec) Path canonical(const path& pval, error_code& ec) canonical path canonical(const path& pval, const path& base = current_path()) If !pval.has_root_name() & !pval.has_root_directory() the function returns absolute(base) / pval.īegin const directory_iterator& begin(const directory_iterator& iter) noexcept īegin(const recursive_directory_iterator& iter) noexcept īoth functions return iter. If !pval.has_root_name() & pval.has_root_directory() the function returns absolute(base).root_name() / pval. If pval.has_root_name() & !pval.has_root_directory() the function returns pval.root_name() / absolute(base).root_directory() / absolute(base).relative_path() / pval.relative_path(). If pval.has_root_name() & pval.has_root_directory() the function returns pval. The function returns the absolute pathname corresponding to pval relative to the pathname base: absolute path absolute(const path& pval, const path& base = current_path())

SEPARATION STUDIO FILE NOT THE SAME SIZE FREE
These free functions in the header do modifying and query operations on paths, files, symlinks, directories, and volumes.
