Public API

The runtime library is not completely internal, also provides a public API. This API is mostly safe, and they may influence common runtime behavior or provide some additional opportunities.

Variables

const BigEndian: bool

Whether the running program's architecture is big-endian.

const LittleEndian: bool

Whether the running program's architecture is little-endian.

const OS: str

The running program's operating system target: one of darwin, linux and so on.
To view possible combinations of OS, run julec tool distos

const Arch: str

The running program's architecture target: one of i386, amd64 and so on.
To view possible combinations of OS, run julec tool distarch

const RCDelta: untyped integer

The reference counting data delta value that must occur per each reference counting operation.

NumCPU

fn NumCPU(): int

Returns the number of logical CPUs usable by the current process.

The set of available CPUs is checked by querying the operating system at process startup. Changes to operating system CPU allocation after process startup are not reflected.
