random(:float, non_neg_integer) :: [float]
random(non_neg_integer, non_neg_integer) :: uint32
Returns a random integer x, min <= x <= max 32bit based
random(non_neg_integer, non_neg_integer, non_neg_integer) :: [uint32]
Returns a random integer x, min <= x <= max 32bit based
Sets the process seed
Called when an application is started.
This function is called when an the application is started using
Application.start/2
(and functions on top of that, such as
Application.ensure_started/2
). This function should start the top-level
process of the application (which should be the top supervisor of the
application’s supervision tree if the application follows the OTP design
principles around supervision).
start_type
defines how the application is started:
:normal
- used if the startup is a normal startup or if the application is distributed and is started on the current node because of a failover from another mode and the application specification key:start_phases
is:undefined
.{:takeover, node}
- used if the application is distributed and is started on the current node because of a failover on the nodenode
.{:failover, node}
- used if the application is distributed and is started on the current node because of a failover on nodenode
, and the application specification key:start_phases
is not:undefined
.
start_args
are the arguments passed to the application in the :mod
specification key (e.g., mod: {MyApp, [:my_args]}
).
This function should either return {:ok, pid}
or {:ok, pid, state}
if
startup is successful. pid
should be the PID of the top supervisor. state
can be an arbitrary term, and if omitted will default to []
; if the
application is later stopped, state
is passed to the stop/1
callback (see
the documentation for the c:stop/1
callback for more information).
use Application
provides no default implementation for the start/2
callback.
