1# Pthread Example

3(See the README.md file in the upper level 'examples' directory for more information about examples.)

5ESP-IDF provides implementations for many standard POSIX Threads (pthread) APIs. These APIs are impmlemented as thin wrappers around FreeRTOS APIs.
6
7This example demonstrates how to create threads using this API, and how to use the ESP-IDF pthreads extension API to set default thread parameters for the related FreeRTOS tasks. For complete details about supported Pthreads APIs, consult the ESP-IDF Programmers Guide.

9## How to use example
10
11### Hardware Required
12
13This example should be able to run on any supported Espressif SoC development board.
14
15### Configure the project
16
17```
18idf.py set-target esp32
19```
20
21(Replace `esp32` with the name of the chip target you are using.)
22
23```
24idf.py menuconfig
25```
26
27### Build and Flash
28
29Build the project and flash it to the board, then run monitor tool to view serial output:
30
31```
32idf.py -p PORT flash monitor
33```
34
35(Replace PORT with the name of the serial port to use.)
36
37(To exit the serial monitor, type ``Ctrl-]``.)
38
39See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
