# TinyThreads
TinyThreads is POSIX threads (pthreads) compatible tiny multi-threading library for 32-bit microcontrollers.
Currently, following processors are supported:
* Intel(Altera) Nios II
* Xilinx Zynq-7000 (Cortex-A9)
* ~~Microchip PIC32 (MIPS32 Architecture)~~

## 削除されている機能 / Dropped features
以下に挙げる機能はTinyThreadsが目指す「小さなマルチスレッド環境」に不要と判断され、
削除された機能です。原則として、将来も対応する予定はありません。
The features below are dropped because they are not useful in "tiny" multi-threading environment.
As a general rule, they have never been supported in the future.
- pthread\_atfork()
- pthread\_cancel()
- pthread\_key\*()
- pthread\_getspecific()
- pthread\_setspecific()
- sem\_open()
- sem\_unlink()
