The atomic_exchange and atomic_exchange_explicit functions seem to be inconsistently missing parameters.

[ Post Summit: ]

Lawrence: Need to write up a list for Pete with details.

Detlef: Should not be New, we already talked about in Concurrency group.

Recommend Open.

Lawrence will handle all issues relating to atomics in a single paper.

LWG will defer discussion on atomics until that paper appears.

Move to Open.

NAD EditorialResolved. Solved by N2992.

Proposed resolution:

Add the appropriate parameters. For example,

bool atomic_exchange(volatile atomic_bool*, bool);
bool atomic_exchange_explicit(volatile atomic_bool*, bool, memory_order);
