proc createThread(t: var Thread[void]; tp: proc () {.thread, nimcall.}) {. ...raises: [ResourceExhaustedError], tags: [], forbids: [].}: Source Edit
proc createThread[TArg](t: var Thread[TArg]; tp: proc (arg: TArg) {.thread, nimcall.}; param: TArg): Creates a new thread t and starts its execution.

Entry point is the proc tp. param is passed to tp. TArg can be void if you don't need to pass any data to the thread.

proc getThreadId(): int {....raises: [], tags: [], forbids: [].}: Gets the ID of the currently running thread. Source Edit
proc handle[TArg](t: Thread[TArg]): SysThread {.inline.}: Returns the thread handle of t. Source Edit
proc joinThread[TArg](t: Thread[TArg]) {.inline.}: Waits for the thread t to finish. Source Edit
proc joinThreads[TArg](t: varargs[Thread[TArg]]): Waits for every thread in t to finish. Source Edit
proc pinToCpu[Arg](t: var Thread[Arg]; cpu: Natural): Pins a thread to a CPU.

In other words sets a thread's affinity. If you don't know what this means, you shouldn't use this proc.
Source Edit
proc running[TArg](t: Thread[TArg]): bool {.inline.}: Returns true if t is running. Source Edit
