Get familiar with assembly language
make to compile or make test to see the functions in action (read reads first 1000 characters of main.c)
- The library must be called libasm.a.
- You must submit a main that will test your functions and that will compile with your library to show that it’s functional.
- You must rewrite the following functions in asm:
- ft_strlen (man 3 strlen)
- ft_strcpy (man 3 strcpy)
- ft_strcmp (man 3 strcmp)
- ft_write (man 2 write)
- ft_read (man 2 read)
- ft_strdup (man 3 strdup, you can call to malloc)
- You must check for errors during syscalls and properly set them when needed
- Your code must set the variable errno properly.
- For that, you are allowed to call the extern ___error or errno_location.
This lib only works on MacOS, but can easily be rewritten for Linux. You only need to change the syscall codes.
