+ * Function:  timer_create
+ *
+ * Description:
+ *   The  timer_create() function creates per-thread timer using the specified
+ *   clock, clock_id, as the timing base. The timer_create() function returns, in
+ *   the location referenced by timerid, a timer ID of type timer_t used to identify
+ *   the timer in timer requests. This timer ID is unique until the timer is
+ *   deleted. The particular clock, clock_id, is defined in <time.h>. The timer
+ *   whose ID is returned will be in a disarmed state upon return from
+ *   timer_create().
+ *
+ *   The evp argument, if non-NULL, points to a sigevent structure. This structure
+ *   is allocated by the called and defines the asynchronous notification to occur.
+ *   If the evp argument is NULL, the effect is as if the evp argument pointed to
+ *   a sigevent structure with the sigev_notify member having the value SIGEV_SIGNAL,
+ *   the sigev_signo having a default signal number, and the sigev_value member
+ *   having the value of the timer ID.
+ *
+ *   Each implementation defines a set of clocks that can be used as timing bases
+ *   for per-thread timers. All implementations shall support a clock_id of
+ *   CLOCK_REALTIME.
+ *
+ * Parameters:
+ *   clockid - Specifies the clock to use as the timing base.
+ *   evp - Refers to a user allocated sigevent structure that defines the
+ *     asynchronous notification.  evp may be NULL (see above).
+ *   timerid - The pre-thread timer created by the call to timer_create().
+ *
+ * Return Value:
+ *   If the call succeeds, timer_create() will return 0 (OK) and update the
+ *   location referenced by timerid to a timer_t, which can be passed to the
+ *   other per-thread timer calls.  If an error occurs, the function will return
+ *   a value of -1 (ERROR) and set errno to indicate the error.
+ *
+ *   EAGAIN - The system lacks sufficient signal queuing resources to honor the
+ *    request.
+ *   EAGAIN - The calling process has already created all of the timers it is
+ *     allowed by this implementation.
+ *   EINVAL - The specified clock ID is not defined.
+ *   ENOTSUP - The implementation does not support the creation of a timer attached
+ *     to the CPU-time clock that is specified by clock_id and associated with a
+ *     thread different thread invoking timer_create().
+ *
+ * Assumptions:
