- There is a set of changes to the standard being proposed under the title
- 1003.1b (the copy I have is draft 0.1, May 19, 1989). This adds the test macro
- S_ISLNK(m), and the function lstat(). stat() and lstat() differ only in that
- stat() never returns information about a symbolic link, whereas lstat() does.
- Because you cannot open a symbolic link, fstat() is like stat() here.
-
- The draft defines two new functions:
-
- int readlink (char *path, char *buf, int buf_size);
-
- int symlink (char *target_path, char *symlink_path);
-
- The functions that operate on links rather than the file pointed to are:
-
- lstat() readlink() rename() remove() rmdir() symlink() unlink()
-
- The effects of the following functions form an open issue:
-
- chown() chmod() link() utime()
