std::ends

科技促进发展：结束

Defined in header ​​
template< class CharT, class Traits > std::basic_ostream<CharT, Traits>& ends( std::basic_ostream<CharT, Traits>& os ​​

将空字符插入输出序列。os好像通过打电话os.put(CharT())...

这是一个只有输出的I/O操作程序，可以用如下表达式调用它out << std::ends对任何out类型std::basic_ostream...

注记

此机械手通常与std::ostrstream，当关联的输出缓冲区需要以空结尾作为C字符串处理时。

不像std::endl，这个机械手不会冲洗溪流。

参数

os-reference to output stream

返回值

os%28在插入空字符%29后引用流。

例

二次

#include <cstdio>
#include <strstream>
int main()
{
    std::ostrstream oss;
    oss << "Sample text: " << 42 << std::ends;
    std::printf("%s\n", oss.str()
    oss.freeze(false // enable memory deallocation
}

二次

产出：

二次

Sample text: 42

二次

另见

ostrstream (deprecated)implements character array output operations (class)
