what is reference count and how to implement it in removing garbage collection??? In C it does not have automatic garbage collection like java.so how to do it in C???

推荐答案

引用计数不是用于删除垃圾收集，而不是即使是去除垃圾，真的。这是一种自动销毁未引用对象的技术。你可以在这里了解它：

在C中实现这种技术没有问题。实际上，这正是使用 COM 。

Reference count is not for removing garbage collection, and not even for removing garbage, really. This is a technique for automated destruction of non-referenced objects. You can learn about it here:
http://en.wikipedia.org/wiki/Reference_counting[^].

There is no a problem to implement this technique in C. Actually, this is exactly what is normally done in C programs using COM.
