+NAME
+ timer_getoverrun
+SYNOPSIS
+ #include <time.h>
+
+ int timer_getoverrun(timer_t timerid);
+
+ Only a single signal shall be queued to the process for a given timer
+ at any point in time. When a timer for which a signal is still pending
+ expires, no signal shall be queued, and a timer overrun shall occur.
+ When a timer expiration signal is delivered to or accepted by a pro-
+ cess, if the implementation supports the Realtime Signals Extension,
+ the timer_getoverrun() function shall return the timer expiration
+ overrun count for the specified timer. The overrun count returned con-
+ tains the number of extra timer expirations that occurred between the
+ time the signal was generated (queued) and when it was delivered or
+ accepted, up to but not including an implementation-defined maximum of
+ {DELAYTIMER_MAX}. If the number of such extra expirations is greater
+ than or equal to {DELAYTIMER_MAX}, then the overrun count shall be set
+ to {DELAYTIMER_MAX}. The value returned by timer_getoverrun() shall
+ apply to the most recent expiration signal delivery or acceptance for
+ the timer. If no expiration signal has been delivered for the timer,
+ or if the Realtime Signals Extension is not supported, the return
+ value of timer_getoverrun() is unspecified.
+
+RETURN VALUE
+ If the timer_getoverrun() function succeeds, it shall return the timer
+ expiration overrun count as explained above.
