Gets a line from the input stream.
basic_istream<Elem, Tr>& getline(
char_type *_Str,
streamsize _Count
);
basic_istream<Elem, Tr>& getline(
char_type *_Str,
streamsize _Count,
char_type _Delim
);
Parameters
_Count
The number of characters to read from strbuf._Delim
The character that should terminate the read if it is encountered before _Count._Str
A string in which to write.
Return Value
The stream (*this).
Remarks
The first of these unformatted input functions returns getline(_Str, _Count, widen('\n')).
The second function extracts up to _Count - 1 elements and stores them in the array beginning at _Str. It always stores the string termination character after any extracted elements it stores. In order of testing, extraction stops:
At end of file.
After the function extracts an element that compares equal to _Delim, in which case the element is neither put back nor appended to the controlled sequence.
After the function extracts _Count - 1 elements.
If the function extracts no elements or _Count - 1 elements, it calls setstate(failbit). In any case, it returns *this.
Example
// basic_istream_getline.cpp
// compile with: /EHsc
#include <iostream>
using namespace std;
int main( )
{
char c[10];
cin.getline( &c[0], 5, '2' );
cout << c << endl;
}
