# Threading
|
|
|
|
The Open Screen Library is **single-threaded**; all of its code is intended to be
|
|
run on a single sequence, with a few exceptions noted below.
|
|
|
|
A library client **must** invoke all library APIs on the same sequence that is
|
|
used to run tasks on the client's
|
|
[TaskRunner implementation](https://chromium.googlesource.com/openscreen/+/refs/heads/master/platform/api/task_runner.h).
|
|
|
|
## Exceptions
|
|
|
|
* The [trace logging](trace_logging.md) framework is thread-safe.
|
|
* The TaskRunner itself is thread-safe.
|
|
* The [POSIX platform implementation](https://chromium.googlesource.com/openscreen/+/refs/heads/master/platform/impl/)
|
|
starts a network thread, and handles interactions between that thread and the
|
|
TaskRunner internally.
