function will block the caller until a grace period has been
detected, according to the semantics of epoch reclamation.
Any objects requiring safe memory reclamation which are logically
deleted are safe for physical deletion following a call to
Fn ck_epoch_barrier 3 . This function will also dispatch all callbacks
that were previously scheduled via
Fn ck_epoch_call 3 .
* epoch was previously initialized with ck_epoch_init.
* stack was previously initialized with ck_stack_init.
record = malloc(sizeof *record);
* We are using an epoch section here to guarantee no
* nodes in the stack are deleted while we are dereferencing
* them. This is needed here because there are multiple writers.
* If there was only one thread popping from the this stack,
* then there is no need to ck_epoch_begin/ck_epoch_end.
/* Logically delete an object. */
s = ck_stack_pop_upmc(stack);
* Wait until no threads could possibly have a reference to the
* object we just popped (assume all threads are simply executing
/* It is now safe to physically delete the object. */
This function has no return value.
Behavior is undefined if the object pointed to by
is not a valid epoch object. The object pointed to by
must have been previously registered via
Fn ck_epoch_register 3 .
