|
|
Options that customize size limits:
|
||
|
|
--atexit-max=<integer> [default: 16]
|
||
|
|
Number of exit handlers that can be registered by atexit().
|
||
|
|
--rtc-callbacks=<integer> [default: 5]
|
||
|
|
Number of RTC callbacks that can be registered.
|

|
|
--events-queue-size=<integer> [default: 64]
