Discussion:

The requirements for the constructor forcondition_variable has severalerror conditions, but the requirements for the constructor forcondition_variable_any has none. Is this difference intentional?

[Summit:]

Move to open, pass to Howard. If this is intentional, a note may behelpful. If the error conditions are to be copied fromcondition_variable, this depends on LWG965⁽ⁱ⁾.

[Post Summit Howard adds:]

The original intention (N2447)was to let the OS return whatever errors it was going to return, and forthose to be translated into exceptions, for bothcondition_variable andcondition_variable_any. I have notreceived any complaints about specific error conditions from vendors onnon-POSIX platforms, but such complaints would not surprise me if they surfaced.

[2009-10 Santa Cruz:]

Leave open. Benjamin to provide wording.

[2010 Pittsburgh:]

We don't have throw clauses for condition variables.

This issue may be dependent on LWG1268⁽ⁱ⁾.

Leave open. Detlef will coordinate with Benjamin.

Consider merging LWG 964,966⁽ⁱ⁾, and1268⁽ⁱ⁾ into asingle paper.
