char* func_name VS char *func_name (what are the differences)

Question

What are the differences between a char pointer function and a pointer function?

char *get_next_line(int fd)
{
    static char *str;
    char        *line;

    if (fd <= 0 || BUFFER_SIZE <= 0)
        return (0);
    
    
}

and

char* get_next_line(int fd)
{
    static char *str;
    char        *line;

    if (fd <= 0 || BUFFER_SIZE <= 0)
        return (0);
    
    
}
