To make one executable look like many executables, BusyBox exploits a seldom-used feature of argument passing to the main C function. Recall that the C main function is defined as follows

为了让一个可执行程序看起来就像是很多可执行程序一样，BusyBox 为传递给 C 的 main 函数的参数开发了一个很少使用的特性。

For method calls, I tried the same three access variations as for field access, with the added variable of using no-argument methods versus passing and returning a value on the method calls.

在方法调用中，我试用了与字段接入相同的三种接入变量，并增加了使用无参数方法变量，而不是在方法调用中传递和返回一个值。

On the other hand, code can't be much more straightforward than passing an argument to a method and examining the result.

另一方面，代码再易懂也不如将参数传给一个方法并检查结果更加直白。
