stdlib: Remove attr_write from mbstows if dst is NULL [BZ: 29265]
|
||
|
|
|
||
|
|
Incorrectly called `__mbstowcs_chk` in the NULL __dst case which is
|
||
|
|
incorrect as in the NULL __dst case we are explicitly skipping
|
||
|
|
the objsize checks.
|
||
|
|
|
||
|
|
As well, remove the `__always_inline` attribute which exists in
|
||
|
|
`__fortify_function`.
