const path& path1() const noexcept;
Returns: A reference to the copy of
p1 stored by the
constructor, or, if none, an empty path
. const path& path2() const noexcept;
Returns: A reference to the copy of
p2 stored by the
constructor, or, if none, an empty path
. const char* what() const noexcept override;
Returns: A string containing
runtime_error::what(). The exact format is unspecified
.Implementations are encouraged but not required to include
path1.native_string()
if not empty,
path2.native_string() if not empty, and
system_error::what() strings in the returned
string
