bugprone-spuriously-wake-up-functions

|
|
=====================================
|
||
|
|
|
||
|
|
Finds ``cnd_wait``, ``cnd_timedwait``, ``wait``, ``wait_for``, or
|
||
|
|
``wait_until`` function calls when the function is not invoked from a loop
|
||
|
|
that checks whether a condition predicate holds or the function has a
|
||
|
|
condition parameter.
|
||
|
|
|
||
|
|
.. code-block: c++
|
||
|
|
|
||
|
|
if (condition_predicate) {
|
||
|
|
condition.wait(lk);
|
||
|
|
}
|
||
|
|
|
||
|
|
.. code-block: c
|
||
|
|
|
||
|
|
if (condition_predicate) {
|
||
|
|
if (thrd_success != cnd_wait(&condition, &lock)) {
|
||
|
|
}
|
||
|
|
}
