module Id : Core_kernel.Identifiable.S with type t = Machine.id

val fork : unit -> unit t

fork () forks the current state.

val switch : Machine.id -> unit t

switch id switches to the state with the given id if such state is alive, otherwise switches to the closest alive ancestor of the state with the given id

val parent : unit -> Machine.id t

parent () returns an identifier of the closest alive parent.

put s changes the current state to s

val get : unit -> Bap.Std.project t

val raise : exn -> 'a t

raise exn raises the machine exception exn, intiating an abonormal control flow

val catch : 'a t -> (exn -> 'a t) -> 'a t

catch x f creates a computation that is equal to x if it terminates normally, and to f e if x terminates abnormally with the exception e.

val project : Bap.Std.project t

project is a computation that results with the project data structure. Note, that Machine is a State monad with the env type equal to project, thus project is a shortcut to get ().

This function is always evaluated in the global context, i.e., there is only one project that is shared by all machine forks.

You can use put project to update the project data structure.

val program : Bap.Std.program Bap.Std.term t

program program representation.

The same as gets Project.program.

val arch : Bap.Std.arch t

arch code architecture.

The same as gets Project.arch.

val args : string array t

args program command line arguments.

val envp : string array t

envp program environment variables.
