Is there any interest in adding a generalized version of worker's
fdqueue to apr-util (this is a FIFO not a stack btw) ???
this is different to the resource list posted by aaron, as it just
manages a work queue.
the api:
apr_status_t apr_queue_init(apr_queue_t **queue,
int queue_capacity,
apr_pool_t *a);
apr_status_t apr_queue_push(apr_queue_t *queue, void *data);
apr_status_t apr_queue_pop(apr_queue_t *queue, void **data);
/* non-blocking versions of above */
apr_status_t apr_queue_trypush(apr_queue_t *queue, void *data);
apr_status_t apr_queue_trypop(apr_queue_t *queue, void **data);
int apr_queue_size(apr_queue_t *queue);
apr_status_t apr_queue_interrupt_all(apr_queue_t *queue);
apr_status_t apr_queue_term(apr_queue_t *queue);
possible improvements will be the ability to push/pop multiple items
off the queue at the same time.
