We can't neither come back nor move in the file descriptor.\n-   We can't use _lseek_, only _read_, _malloc_, _free_, nor the [libft](https://github.com/Link-Wolf/libft)\n-   We can't use globals variables nor FILE structure, but static variables are allowed\n-   The buffer size used by _read_ can be changed\n-   Call the function in a loop will then allow to read the text available on a file descriptor one line at a time until the end of the text, no matter\n    the size of either the text or one of its lines\n\nThere were also two additional bonus features\n\n-   Be able to read multiple file descriptors at the same time\n-   Only use **one** static variable\n    \u003cbr /\u003e\n\n\u003cp align=\"right\"\u003e(\u003ca href=\"#top\"\u003eback to top\u003c/a\u003e)\u003c/p\u003e\n\n\u003c!-- GETTING STARTED --\u003e\n\n## Getting Started\n\nBecause it's a simple C function, there isn't much to say here\n\n### Prerequisites\n\nHaving a C compiler like cc, gcc or clang\n\n### Installation\n\n1.
