A reference to a null-terminated string. It can be constructed from a C
|
||||
string or ``std::string``.
|
||||
|
||||
You can use one of the following type aliases for common character types:
|
||||
|
||||
+---------------+-----------------------------+
|
||||
| Type | Definition |
|
||||
+===============+=============================+
|

|
||||
| wcstring_view | basic_cstring_view<wchar_t> |
|

+---------------+-----------------------------+
|
||||
|

This class is most useful as a parameter type to allow passing
|

different types of strings to a function, for example::
