Unclear semantics of read_symlink on error: 15.27 [fs.op.read_symlink] has: Returns: If p resolves to a symbolic link, a path object containing the contents of that symbolic link. Otherwise path(). and also [Note: It is an error if p does not resolve to a symbolic link. -- end note]
I do not believe path() can be a valid return for the overload not taking error_code.
Strike "Otherwise path()."
[2014-02-09, Beman Dawes provides wording]
[2014-02-13 LWG/SG-3 Issaquah: Proposed wording accepted.]
Proposed resolution:Change 15.27 [fs.op.read_symlink]:
presolves to a symbolic link, a
pathobject containing the contents of that symbolic link.
OtherwiseThe signature with argument
path()if an error occurs.
Throws: As specified in Error reporting. [Note: It is an error if
pdoes not resolve to a symbolic link. — end note]
