First steps

By default, your main() should look like this

int	main(void)
{
	ft_memman_init();

	/* YOUR CODE */

	ft_force_buff();
	ft_memman_clean();
	return (0);
}

Same as in test.c

• Why? And what does it mean?

  • I wrote a simple memory manager. In short, it collects and stores all the memory allocated by malloc(). All other functions in the library (again: by default) use this manager. At the beginning of each program, it must be initialized and deleted at the end. This is exactly what the ft_memman_init() and ft_memman_clean() functions do. And if you are going to use my libft, you probably should use them too.

  Take a look at the Memory manager page for details.

  • For best performance, ft_printf () uses output buffer mechanics. And for extremely performance (again: by defaul) it doesn’t guarantee to print something in stdout. I set output buffer size at 8192 (8 kb). If it is filled, it is displayed (8 kb at a time). And in order to guarantee that everything that we wanted to print will really be printed, it is necessary to call ft_force_buff() before exit() the program.

  Take a look at the Output buffer page for details.

• I started using/exploring your libft, and found that all the functions declared in ft_libc.h implemented like this ft_strlen.c. Why and what for?

  • By libft subject and in all next C projects, we can't use functions from libc (except some basic like malloc(), free(), write() and e.g.). So all this functions have my own (and fully correct) implementation.
  • But this is a good library! And I will continue to use it in all of my next C projects (even after school 21). So it would be nice to have an easy way to get all the power of the C language and use libc functions instead of mine!
  • In addition, it’s nice to have a simple way to explore how the program’s performance will change when switching from self-written to standard functions.

• What if I don't want to use the memory manager or want the printf to immediately output information? And how can I switch between self-written and standard functions?

  • Don't worry! It's really easy to change! Take a look at the libft_mod page for an answer!
