egptr

性病：基本[医]流：：eback，gptr，egptr

char_type* eback() const;(1)​
char_type* gptr() const;(2)​
char_type* egptr() const;(3)​

返回定义GET区域的指针。

1%29返回指向GET区域开头的指针。

2%29返回指向当前字符%28的指针获取指针在GET区域的%29。

3%29在GET区域结束后返回指针。

参数

%280%29

返回值

1%29指向GET区域开头的指针。

2%29指向当前字符%28的指针获取指针在GET区域的%29。

3%，29，指针超过了该区域的结束。

注记

名称“gptr”和“egptr”指的是get区域，而名称“eback”指的是putback区域的末尾：从gptr退一步，字符可以放回到eback为止。

例

另见

pbasepptrepptrreturns a pointer to the beginning, current character and the end of the put area (protected member function)
