Substantially, what can be done to support multiple c-shared libraries? What's the problem at the root that cannot be solved? If this has been already discussed, please give me a pointer. The underlying problem is that currently each Go runtime assumes it has the complete information of all...
可以看到,在 main 函数中,我们试着调用 result 这个变量,但是因为这个变量是在 multipleTwo 函数中定义的,在 main 函数中就不能调用,编译会出错。 记住:在函数里定义的变量只能在函数内部使用,我们称之为局部变量,英语是 local variable。local 表示“局部的,本地的”,variable 表示“变量”。 全局变量(请避免使...
