Constants

ended_exited

const ended_exited: int = 0

What wait writes into how for a child that exited: value is its exit code.

ended_signalled

const ended_signalled: int = 1

What wait writes into how for a child that a signal ended: value is the signal’s number.

A child a kernel ended for a fault is reported this way too, with the number POSIX raises for that fault – 11 (SIGSEGV) for an address it could not touch, 4 (SIGILL) for an instruction it could not run, 7 (SIGBUS), 8 (SIGFPE) – so that Status.Signalled(11) means what it means on every POSIX host.

ended_timed_out

const ended_timed_out: int = 2

What wait writes into how for a child it stopped because its deadline passed.

group_inherit

const group_inherit: i64 = -1

What spawn is handed as pgid to leave the child in this program’s process group.

group_new

const group_new: i64 = 0

What spawn is handed as pgid to make the child the leader of a new group, numbered by its pid.

id_group

const id_group: int = 1

The group the program acts as: the effective group.

id_real_group

const id_real_group: int = 3

The group of the user who started the program: the real group.

id_real_user

const id_real_user: int = 2

The user who started the program – the real user. It differs from id_user only in a program that changed who it acts as, a set-user-ID one or one that called set_id; on a target that keeps one user per process the two are the same number.

id_user

const id_user: int = 0

What get_id and set_id are asked about: the user the program acts as – the effective user, the one a filesystem checks a permission against and makes a new file’s owner.

Types

Text

struct Text
    ptr: *u8
    len: usize

A run of bytes, lent: where it starts and how many there are. Laid out as C lays out a pointer followed by a size_t, which is what a supplier written in C reads it as.
