`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)

kill(+process_or_pid,+atom_or_integer) - zero_or_one

`kill/1`

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

Compilation flags:
