示例1:
void interface5::internal::task_base::destroy( task& victim ) {
__TBB_ASSERT( victim.prefix().ref_count== (ConcurrentWaitsEnabled(victim) ? 1 : 0), "Task being destroyed must not have children" );
__TBB_ASSERT( victim.state()==task::allocated, "illegal state for victim task" );
task* parent = victim.parent();
victim.~task();
if( parent ) {
__TBB_ASSERT( parent->state()==task::allocated, "attempt to destroy child of running or corrupted parent?" );
parent->internal_decrement_ref_count();
// Despite last reference to *parent removed, it should not be destroyed (documented behavior).
}
governor::local_scheduler()->free_task<no_hint>( victim );
}示例2:
void interface5::internal::task_base::destroy( task& victim ) {
// 1 may be a guard reference for wait_for_all, which was not reset because
// of concurrent_wait mode or because prepared root task was not actually used
// for spawning tasks (as in structured_task_group).
__TBB_ASSERT( (intptr_t)victim.prefix().ref_count <= 1, "Task being destroyed must not have children" );
__TBB_ASSERT( victim.state()==task::allocated, "illegal state for victim task" );
task* parent = victim.parent();
victim.~task();
if( parent ) {
__TBB_ASSERT( parent->state()==task::allocated, "attempt to destroy child of running or corrupted parent?" );
parent->internal_decrement_ref_count();
// Even if the last reference to *parent is removed, it should not be spawned (documented behavior).
}
governor::local_scheduler()->free_task<no_hint>( victim );
