FT_PUTCHAR_FD (simplified)

SYNOPSIS
    void ft_putchar_fd(char c, int fd);
DESCRIPTION

    fd: file descriptor on which to write
RETURN VALUES
    ft_putchar_fd() does not return anything.
AUTHORIZED EXTERNAL FUNCTIONS
    write(2)

Understandable explanation

This one is pretty straight forward, you already know how to write the ft_putchar() function, if you don't remember, look back at what you did during your Piscine.

Hints

Take a look at the man for the write(2) function, the first parameter is... you guessed it ! A file descriptor, so I mean, do you really need to have the code for this ?

I hope you can figure it out.
