ck_epoch_recyclereturn an epoch record that may be used by caller

Concurrency Kit (libck, -lck)

#include <ck_epoch.h>

ck_epoch_record_t *
ck_epoch_recycle(ck_epoch_t *epoch);

The (3) function attempts to return an unused epoch record object for use by the caller. These epoch records were associated with previous calls to the (3) function.

#include <ck_epoch.h>
#include <stdlib.h>

 * epoch was previously initialized with ck_epoch_init.
ck_epoch_t *epoch;

	ck_epoch_record_t *record;

	record = ck_epoch_recycle(&epoch);
	if (record == NULL) {
		record = malloc(sizeof *record);
		if (record == NULL)

		ck_epoch_register(&epoch, record);

	 * After we are done, we will unregister the record so it
	 * can be used by other new participants in the epoch system
	 * provided by the object pointed to by "epoch".
	ck_epoch_unregister(&epoch, record);

This function returns a pointer to a ck_epoch_record_t object. If no unused record was found to be associated with the object pointed to by epoch, then the function will return NULL.

Behavior is undefined if the object pointed to by epoch is not a valid epoch object.
