Command (frama-c.Frama_c

Pretty from files

val pp_from_file : Stdlib.Format.formatter -> Filepath.t -> unit

pp_from_file fmt file dumps the content of file into the fmt. Exceptions in pp are re-raised after closing.

Timing Utility

type timer = float Stdlib.ref

val time : ?rmax:timer -> ?radd:timer -> ('a -> 'b) -> 'a -> 'b

Compute the elapsed time with Sys.time. The rmax timer is maximized and the radd timer is cumulated. Computed result is returned, or exception is re-raised.

System commands

type process_result =

| Not_ready of unit -> unit
| Result of Unix.process_status
(*
Not_ready f means that the child process is not yet finished and may be terminated manually with f ().
*)

val async : 
  ?stdout:Stdlib.Buffer.t ->
  ?stderr:Stdlib.Buffer.t ->
  string ->
  string list ->
  unit ->
  process_result

Same arguments as Unix.create_process.

returns
a function to call to check if the process execution is complete. You must call this function until it returns a Result to prevent Zombie processes. When this function returns a Result, the stdout and stderr of the child process will be filled into the arguments buffer.

raises Sys_error
when a system error occurs

before 31.0-Gallium
this function was named command_async

val spawn : 
  ?timeout:int ->
  ?stdout:Stdlib.Buffer.t ->
  ?stderr:Stdlib.Buffer.t ->
  string ->
  string list ->
  Unix.process_status

Same arguments as Unix.create_process. When this function returns, the stdout and stderr of the child process will be filled into the arguments buffer.

raises Sys_error
when a system error occurs

raises Async.Cancel
when the computation is interrupted or on timeout

before 29.0-Copper
Async.Cancel was Db.Cancel

before 31.0-Gallium
this function was named command
