explicit latch( ptrdiff_t value );	(1)	(concurrency TS)
latch( const latch & ) = delete;	(2)	(concurrency TS)

1) Constructs a latch and initializes its internal counter.

2) Copy constructor is deleted. latch is not copyable.

Parameters

value

-

the initial value of the internal counter; must be non-negative
