Discussion:

The requirements for the constructor for condition_variable has several error conditions, but the requirements for the constructor for condition_variable_any has none. Is this difference intentional?

[ Summit: ]

Move to open, pass to Howard. If this is intentional, a note may be helpful. If the error conditions are to be copied from condition_variable, this depends on LWG 965.

[ Post Summit Howard adds: ]

The original intention (N2447) was to let the OS return whatever errors it was going to return, and for those to be translated into exceptions, for both condition_variable and condition_variable_any. I have not received any complaints about specific error conditions from vendors on non-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 LWG 1268.

Leave open. Detlef will coordinate with Benjamin.

Consider merging LWG 964, 966, and 1268 into a single paper.
