stringstream::getline()

[wolfv]

This page shows that stringstream has a getline() method:
http://www.cplusplus.com/reference/sstream/stringstream/

But when I try using it, this compile error:

rdbuf3.cpp: In function ‘int main()’:
rdbuf3.cpp:26:23: error: no matching function for call to ‘std::__cxx11::basic_stringstream<char>::getline(char* [128], int)’
   ss.getline(line, 128);

source code:

#include <iostream>
#include <sstream>

int main()
{
  std::stringstream ss;
  char* line[128];

  ss << "line1\nline2\n";

  ss.getline(line, 128);  //error: no matching function for call to ‘std::__cxx11::basic_stringstream<char>::getline(char* [128], int)’
  std::cout << "first line = " << line << "\n";
}

How to fix the compile error?

Thank you.

line is an array of pointers-to-char and getline doesn't know what to do with an array of pointers-to-char. It should probably be an array of char.

That fixed it!

Thanks cire.
