NAME¶

std::barrier::wait - std::barrier::wait

Synopsis¶

void wait( arrival_token&& arrival ) const; (since C++20)

If arrival is associated with the phase synchronization point for the current phase
of *this, blocks at the synchronization point associated with arrival until the
phase completion step of the synchronization point's phase is run.

Otherwise, if arrival is associated with the phase synchronization point for the
immediately preceding phase of *this, returns immediately.

Otherwise, i.e. if arrival is associated with the phase synchronization point for an
earlier phase of *this or any phase of a barrier object other than *this, the
behavior is undefined.

Parameters¶

arrival - an arrival_token obtained by a previous call to arrive on the same barrier

Return value¶

(none)

Exceptions¶

Throws std::system_error with an error code allowed for mutex types on error.
