Given
e
, produces a suitable value that is not equivalent to
eof
.
This function is typically used when a value other than
eof
needs to be returned, such as in implementations of
std::basic_streambuf::overflow()
.
See
CharTraits
for the general requirements on character traits for
X::not_eof
.
Parameters
| e | - | value to analyze |
Return value
e
if
e
and
eof
value are not equivalent, or some other non-eof value otherwise.
Complexity
Constant.
