Public predicates

create/3

Creates a new process from the given executable and list of arguments. Supported options are process(Pid), stdin(Stream), stdout(Stream), and stderr(Stream).

Compilation flags:
static
Template:
create(Executable,Arguments,Options)
Mode and number of proofs:
create(+atom,+list(atom),+list(compound)) - zero_or_one

wait/2

Waits for a process to terminate and retrieves its exit status.

Compilation flags:
static
Template:
wait(Process,Status)
Mode and number of proofs:
wait(+process_or_pid,-integer) - zero_or_one

kill/2

Kills the given process with the specified signal (an integer or one of the following atoms: sighup, sigint, sigkill, or sigterm).

Compilation flags:
static
Template:
kill(Process,Signal)
Mode and number of proofs:
kill(+process_or_pid,+atom_or_integer) - zero_or_one

kill/1

Kills the given process using the default signal (sigkill).

Compilation flags:
static
Template:
kill(Process)
Mode and number of proofs:
kill(+process_or_pid) - zero_or_one

Protected predicates

(none)

Private predicates
