Majestic plugins for OpenIPC

Experimental system for creating open source plugins for Majestic

Important information:

• At the moment, examples of plugins have been implemented only for the most popular processors today.
• Nothing prevents everyone and enthusiasts from adding them to other processors and actively developing them.
• By default, the plugin system is disabled and does not contribute any actions to the main operation of the device.

---

Example function:

• New functions can be added to vendor/custom.c
• RETURN is a macro to simplify the plugin response output.

static void get_example(const char *value) {
	RETURN("plugin get_example: %s", value);
}

static table custom[] = {
	[...]
	{ "example", &get_example },
};

Example result:

root@openipc-ssc337de:~# echo example test123 | nc localhost 4000
plugin get_example: test123
