* See http://www.FreeRTOS.org/FreeRTOS-Plus/FreeRTOS_Plus_TCP/UDP_CLI.html

* A simple generic mechanism is used that allocates a structure (see the

*
* The structure associates a function with a data value. See the

* The function is used to manipulate the data. At the time of writing two
* functions can be used - these are prvIncrementEventCount() which simply
* increments the data each time it is called, and prvStoreLowest() which
* sets the data to the lowest value of an input parameter ever seen. For
* example, to store the lowest ever number of free network buffer descriptors
* the parameter value is the current number of network buffer descriptors.
*
* The trace macros themselves are defined in DemoIPTrace.h and just invoke

/*
* This file, along with DemoIPTrace.c, provides a basic example use of the
* FreeRTOS+TCP trace macros. The statistics gathered here can be viewed in
* the command line interface.
* See http://www.FreeRTOS.org/FreeRTOS-Plus/FreeRTOS_Plus_TCP/UDP_CLI.html
*
* A simple generic mechanism is used that allocates a structure (see the
* ExampleDebugStatEntry_t definition below) to each ID defined in this file.
* The structures are stored in an array (see the xIPTraceValues[] array in
* DemoIPTrace.c).
*
* The structure associates a function with a data value. See the
* vPerformAction and ulData members of ExampleDebugStatEntry_t respectively.
* The function is used to manipulate the data. At the time of writing two
* functions can be used - these are prvIncrementEventCount() which simply
* increments the data each time it is called, and prvStoreLowest() which
* sets the data to the lowest value of an input parameter ever seen. For
* example, to store the lowest ever number of free network buffer descriptors
* the parameter value is the current number of network buffer descriptors.
*
* The trace macros themselves are defined in this file and just invoke
* vExampleDebugStatUpdate(), passing in an ID value. vExampleDebugStatUpdate()
* then just executes the function associated with that value (prvStoreLowest(),
* prvIncrementEventCount(), etc.) as defined in the xIPTraceValues[] array.

* This file contains the common functions for plain text, basic TLS, and mutual

* demo creates a singe application task that loops through a set of examples
* demonstrating how to the connect to the server, send a few types of requests to
* the server (GET, HEAD, PUT, POST), and disconnect from the server again. All
* of the responses and their associated HTTPS response status codes are printed
* to the console.
*
* The plain text HTTP demo does not authenticate the server nor the client. The
* basic TLS HTTPS demo builds on top of the plain text demo, adding broker
* authentication and encryption. The mutual authentication HTTPS demo builds on

- rpcap://devicename [opens the selected device devices available on the local host, without using the RPCAP protocol]
- rpcap://host/devicename [opens the selected device available on a remote host]
- rpcap://host:port/devicename [opens the selected device available on a remote host, using a non-standard port for RPCAP]
- adaptername [to open a local adapter; kept for compability, but it is strongly discouraged]
- (NULL) [to open the first local adapter; kept for compability, but it is strongly discouraged]
The formats allowed by the pcap_findalldevs_ex() are the following:
- file://folder/ [lists all the files in the given folder]
- rpcap:// [lists all local adapters]
- rpcap://host:port/ [lists the devices available on a remote host]
Referring to the 'host' and 'port' paramters, they can be either numeric or literal. Since
IPv6 is fully supported, these are the allowed formats:
- host (literal): e.g. host.foo.bar
- host (numeric IPv4): e.g. 10.11.12.13
- host (numeric IPv4, IPv6 style): e.g. [10.11.12.13]
- host (numeric IPv6): e.g. [1:2:3::4]
- port: can be either numeric (e.g. '80') or literal (e.g. 'http')
Here you find some allowed examples:
- rpcap://host.foo.bar/devicename [everything literal, no port number]
- rpcap://host.foo.bar:1234/devicename [everything literal, with port number]
- rpcap://10.11.12.13/devicename [IPv4 numeric, no port number]

* @file atomic.h
* @brief FreeRTOS atomic operation support.
*
* Two implementations of atomic are given in this header file:
* 1. Disabling interrupt globally.
* 2. ISA native atomic support.
* The former is available to all ports (compiler-architecture combination),
* while the latter is only available to ports compiling with GCC (version at

*
* User can select which implementation to use by:
* setting/clearing configUSE_ATOMIC_INSTRUCTION in FreeRTOSConfig.h.
* Define AND set configUSE_ATOMIC_INSTRUCTION to 1 for ISA native atomic support.
* Undefine OR clear configUSE_ATOMIC_INSTRUCTION for disabling global interrupt
* implementation.

- Dot notation for IP addresses:

See https://freertos.org/https/ for further information.
Contains projects that demonstrate the IoT HTTPS library.
- Securing HTTPS Communication -
The Hypertext Transfer Protocol (HTTP) is a widely used protocol for application
such as home media to interact with web servers. The Hypertext Transfer Protocol
Secure (HTTPS) is an extension to HTTP, adding secure element to the connection.
HTTPS is encrypted with Transport Layer Security (TLS), which also requires server
authentication. In addition to server authentication, mutual authentication
authenticates the identity of both the server and the client.
- Pre-configured HTTPS Example Projects -
The examples contained in subdirectories from here demonstrate the concepts
described above one at a time. The first example demonstrates plain text
HTTP (insecure) communication, the second example builds on the first to
introduce weak server authentication, and the third example builds on the second to
introduce strong mutual authentication. Note: It is our recommendation to always
use strong mutual authentication in any Internet of Things (IoT) application. The
plain text project is only provided to validate HTTP communication can be
established prior to introducing encryption and authentication, and to allow the
HTTP packets to be observed using a network packet sniffer such as Wireshark for
those who wish to do so. The first two projects are in no way intended to be
examples suitable for production use.
