| class directory_entry; |
(since C++17) | |
Represents a directory entry. The object stores a path as a member and may also store additional file attributes (hard link count, status, symlink status, file size, and last write time) during directory iteration.
Contents |
[edit] Member functions
| constructs a directory entry (public member function) | |
| (destructor) |
default destructor (public member function) |
Modifiers | |
| assigns contents (public member function) | |
| assigns contents (public member function) | |
| sets the filename (public member function) | |
| updates the cached file attributes (public member function) | |
Observers | |
| returns the path the entry refers to (public member function) | |
| checks whether directory entry refers to existing file system object (public member function) | |
| checks whether the directory entry refers to block device (public member function) | |
| checks whether the directory entry refers to a character device (public member function) | |
| checks whether the directory entry refers to a directory (public member function) | |
| checks whether the directory entry refers to a named pipe (public member function) | |
| checks whether the directory entry refers to an other file (public member function) | |
| checks whether the directory entry refers to a regular file (public member function) | |
| checks whether the directory entry refers to a named IPC socket (public member function) | |
| checks whether the directory entry refers to a symbolic link (public member function) | |
| returns the size of the file to which the directory entry refers (public member function) | |
| returns the number of hard links referring to the file to which the directory entry refers (public member function) | |
| gets the time of the last data modification of the file to which the directory entry refers (public member function) | |
| status of the file designated by this directory entry; status of the file/symlink designated by this directory entry (public member function) | |
| (removed in C++20)(removed in C++20)(removed in C++20)(removed in C++20)(removed in C++20)(C++20) |
compares two directory entries (public member function) |
[edit] Non-member functions
| performs stream output on a directory entry (function) |
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 3171 | C++17 | directory_entry couldn't be inserted by operator<< because of LWG2989
|
output enabled again |
