+ * Name: pthread_getschedparam
+ *
+ * Description:
+ *   The pthread_getschedparam() functions will get the scheduling policy and
+ *   parameters of threads. For SCHED_FIFO and SCHED_RR, the only required
+ *   member of the sched_param structure is the priority sched_priority.
+ *
+ *   The pthread_getschedparam() function will retrieve the scheduling
+ *   policy and scheduling parameters for the thread whose thread ID is
+ *   given by 'thread' and will store those values in 'policy' and 'param',
+ *   respectively. The priority value returned from pthread_getschedparam()
+ *   will be the value specified by the most recent pthread_setschedparam(),
+ *   pthread_setschedprio(), or pthread_create() call affecting the target
+ *   thread. It will not reflect any temporary adjustments to its priority
+ *   (such as might result of any priority inheritance, for example).
+ *
+ *   The policy parameter may have the value SCHED_FIFO, or SCHED_RR
+ *   (SCHED_OTHER and SCHED_SPORADIC, in particular, are not supported).
+ *   The SCHED_FIFO and SCHED_RR policies will have a single scheduling
+ *   parameter, sched_priority.
+ *
+ * Input Parameters:
+ *   thread - The ID of thread whose scheduling parameters will be queried.
+ *   policy - The location to store the thread's scheduling policy.
+ *   param  - The location to store the thread's priority.
+ *
+ * Returned Value:
+ *   0 if successful.  Otherwise, the error code ESRCH if the value specified
+ *   by thread does not refer to an existing thread.
+ *
+ * Assumptions:
