Config

None means current WP option default. Some 0 means prover default.

type config = {
valid : bool;
timeout : int option;
stepout : int option;
}
val current : unit -> config

Current parameters

val default : config

all None

val get_timeout : ?kf:Frama_c_kernel.Kernel_function.t -> smoke:bool -> config -> int

0 means no-timeout

val get_stepout : config -> int

0 means no-stepout
