问题描述
我的任务是将一些C代码更新为C ++,很好奇,在ifstream中,C FILE *的rewind方法的等效方法或实现是什么?
I've been tasked to update some C code to C++ and was curious, what is the equivalent method or implementation of C FILE *'s rewind method within ifstream?
推荐答案
这将是 seekg
(设置获取指针)或 seekp
(设置put指针)。在这两种情况下,传递0作为参数,将指针设置为文件的开头。
That would be either seekg
(sets the get-pointer) or seekp
(sets the put pointer). In both cases, passing 0 as parameter results in the pointer being set to the beginning of the file.
