SUMMARY
=======

The sample code below illustrates how to use the string::getline STL function in
Visual C++.

MORE INFORMATION
================

Required Header
---------------

      <string>

Prototype
---------

     template<class _E, class _TYPE, class _A> inline
     basic_istream<_E, _TYPE>& getline( basic_istream<_E, _TYPE>& Istream,
                               basic_string<_E, _TYPE, _A>& Xstring,
                               const _E _D=_TYPE::newline());

NOTE: The class/parameter names in the prototype may not match the version in the
header file. Some have been modified to improve readability.

Description
-----------

The getline function creates a string containing all of the characters from the
input stream until one of the following situations occurs:

 - End of file.

 - The delimiter is encountered.

 - is.max_str() elements have been extracted.

Sample Code
-----------

   #if _MSC_VER > 1020   // if VC++ version is > 4.2

   void main()
   {
       string s1;
       cout << "Enter a sentence (use <space> as the delimiter):";
       getline(cin,s1, ' ');
       cout << "You entered: " << s1;
   }

Program Output is:

Enter a sentence (use <space> as the delimiter): A_space_at_the_end.
You entered: A_space_at_the_end.
