Execution contexts

type t

An evaluation context represent all the information maintained by shexp_process in order to evaluate a process description.

This consists of:

stdin, stdout, stderr
the current working directory
the unix environment variables

module Working_dir : sig ... end

val create : 
  ?stdin:Unix.file_descr ->
  ?stdout:Unix.file_descr ->
  ?stderr:Unix.file_descr ->
  ?cwd:Working_dir.t ->
  ?unix_env:(string * string) list ->
  unit ->
  t

Creates a new execution context. Non-specified fields are captured from the environment of current running program.

val dispose : t -> unit

In order to safely maintain several working directories inside the same system process, shexp keeps a file descriptor of the working directory of the context. You need to dispose of an execution context in order to close this file descriptor.
