rawthreads

nimony/lib/std/rawthreads.nim

• const nativeThreads: bool

  Whether threads here are the runtime's own clone(2) rather than an OS thread library's. True on the native (arkham + nifasm) backend, which links no libc and therefore has no pthreads; false everywhere else, nimony c included — that build is raw-syscall too, but libc is still linked.

• type RawThread = object
    sys: SysThread
    dataFn: proc (arg: pointer) {.nimcall.}
    data: pointer

• proc create(t: out RawThread; fn: proc (arg: pointer) {.nimcall.}; arg: pointer; stackSize: int64; pinnedToCpu: int64)

  Spawns a thread running fn(arg). stackSize selects a custom stack (0 → OS default). pinnedToCpu requests CPU affinity where supported (-1 leaves scheduling to the OS).

• proc join(t: var RawThread)

  Waits for the thread t to finish.

• proc getThreadId(): int64

  Gets the ID of the currently running thread.
