/*
* Bacula job queue routines.
*
+ * This code consists of three queues, the waiting_jobs
+ * queue, where jobs are initially queued, the ready_jobs
+ * queue, where jobs are placed when all the resources are
+ * allocated and they can immediately be run, and the
+ * running queue where jobs are placed when they are
+ * running.
+ *
* Kern Sibbald, July MMIII
*
* Version $Id$
* adapted from "Programming with POSIX Threads", by
* David R. Butenhof
*
- * Example:
- *
- * static jobq_t jq; define job queue
- *
- * Initialize queue
- * if ((stat = jobq_init(&jq, max_workers, job_thread)) != 0) {
- * Emsg1(M_ABORT, 0, "Could not init job work queue: ERR=%s\n", strerror(errno));
- * }
- *
- * Add an item to the queue
- * if ((stat = jobq_add(&jq, jcr)) != 0) {
- * Emsg1(M_ABORT, 0, "Could not add job to queue: ERR=%s\n", strerror(errno));
- * }
- *
- * Terminate the queue
- * jobq_destroy(jobq_t *jq);
