[DATA-PLUG] - A C example of how to utilize shared libraries

About this program

What is [DATA-PLUG]?

[DATA-PLUG] is a sort of simplified data fetcher from databases installed as plugins.

What is [DATA-PLUG] propose?

[DATA-PLUG] is a somewhat easy example of how to use shared libraries while showing the benefits of them.

How exactly does it achieve that?

This example utilizes the ability of dynamically loaded library as plugins for our program, with the benefit of adding functionality to it.

The logic behind

Every database API is installed as a .plugin (how to compile them as this is shown in the Makefile) inside the plugins folder, their APIs are limited only to these functions: [get_info, get_name].

[get_info]:

Its declaration is as follow: char* get_info(const char* search)

It should find all the information related to the searched word and formated as desired, but it must be returned as a string allocated in the heap (for this we have the handy macro create_string insde the header plugins.h).

[get_name]:

Its declaration is as follow: char* get_name()

Its only purpose is to return the database name.
