EventConfig::setMaxDispatchInterval — Prevents priority inversion
$max_interval
,
int
$max_callbacks
,
int
$min_priority
)Prevents priority inversion by limiting how many low-priority event callbacks can be invoked before checking for more high-priority events.
Note:
Available since libevent 2.1.0-alpha .
max_interval
An interval after which Libevent should stop running callbacks and check
for more events, or
0
, if there should be no such interval.
max_callbacks
A number of callbacks after which Libevent should stop running callbacks
and check for more events, or
-1
, if there should be no such limit.
min_priority
A priority below which
max_interval
and
max_callbacks
should not be enforced. If this is set to
0
, they are enforced for events of every priority; if it's set to
1
, they're enforced for events of priority
1
and above, and so on.
Returns TRUE on success, otherwise FALSE.
