Config

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

Sourcetype config = {
  1. valid : bool;
  2. timeout : float option;
  3. stepout : int option;
  4. memlimit : int option;
}
Sourceval current : unit -> config

Current parameters

Sourceval default : config

all None

Sourceval get_timeout : ?kf:Frama_c_kernel.Kernel_function.t -> smoke:bool -> config -> float

0.0 means no-timeout

Sourceval get_stepout : config -> int

0 means no-stepout

Sourceval get_memlimit : config -> int

0 means no-memlimit
