Class Shell_uq.call_engine

class call_engine : ?ignore_error_code:bool ->
       ?mode:Shell_sys.group_mode ->
       ?stdin:Shell.producer ->
       ?stdout:Shell.consumer ->
       ?stderr:Shell.consumer ->
       Shell_sys.command list ->
       Unixqueue.event_system ->
       [Shell_sys.job_status] job_handler_engine_type

This engine corresponds to Shell.call. The command list is executed until the job is done. In this case, the status of the engine changes to `Done or `Error. If not ignore_error_code, failed jobs are reported by the error status `Error Subprocess_failure. If ignore_error_code, failed jobs are ignored, and result in the status `Done (however, jobs terminated by signals are still reported as errors).

For the other arguments see Shell.call.

When the engine goes to `Error or `Aborted, the job is terminated ( Shell_sys.abandon_job ).
