Discussion:

33.7.5 [thread.condition.condvarany]/4 says, in part, that condition_variable_any() throws an exception "if any native handle type manipulated is not available".

I don't know what that means. Is this intended to say something different from the analogous words for condition_variable() [33.7.4 [thread.condition.condvar]/4], "if some non-memory resource limitation prevents initialization"? If not, it should be worded the same way.

[2012, Kona]

Copy the corresponding wording from the condition_variable constructor in 33.7.4 [thread.condition.condvar] p4.

Move to Review.

Concurrency move to Ready.

Proposed resolution:

This wording is relative to N3337.

1. Change 33.6.4.3 [thread.timedmutex.requirements]/4 as indicated:

   condition_variable_any();
   

   […]

   -4- Error conditions:

   • resource_unavailable_try_again — if any native handle type manipulated is not available if some non-memory resource limitation prevents initialization.
   • operation_not_permitted — if the thread does not have the privilege to perform the operation.
