Converts
c
to
char_type
. If there is no equivalent
char_type
value (such as when
c
is a copy of the
eof()
value), the result is unspecified.
See
CharTraits
for the general requirements on character traits for
X::to_char_type
.
Parameters
| c | - | value to convert |
Return value
A value equivalent to c .
Complexity
Constant.
