Question about "basic_istream"
I am checking how basic_istream put out the _streambuf value ,i only found this

-----------------------------------
explicit
basic_istream(__streambuf_type* __sb)
: _M_gcount(streamsize(0))
{ this->init(__sb); }
-----------------------------------

this->init(__sb) is the function to put out the value, where is this function's source code?
[解决办法]
你是在什么环境下看的? 没有<跳转到定义>的功能么?
[解决办法]
VS IDE中，在不明白的符号上点鼠标右键，选转到定义。

[解决办法]
在基类或者本类中查找init
