Hello,

Please use [ CODE ] [ /CODE ] tags to mark code, so it get well formated.

Standard functions reside in std namespace so, you have to add

using namespace std;

after your includes

#include <iostream>
#include <string>
#include <fstream>
using namespace std;

In Readini you're missing an ')';
line:

file.getline(&(buf[0], 300);

You may write Readini like:

String Readini(ifstream &file)
{
	char buf[300]; // up to 300 bytes per line of input
	file.getline(buf, 300);
	return String(buf);
}

In DoLoadFunctions:
inline - is a C++ keyword, so you can't have a variable with that name;
break - it's a C++ keyword, not a function;
Correct DoLoadFunctions would be

int DoLoadFunctions()
{
	String file = "learn.ini";
	ifstream inifile(file);
	while (1)
	{
		String inl = Readini(inifile);
		if (inifile.eof() == true)
			break;
	}
	inifile.close();
	PromptOK("This is a test");
	return 0;
}

You may use U++ functions so you don't have to mix STL code with U++. If you want to read one byte at a time you may use use the following code:

FileIn fi;
fi.Open("learn.ini");
while (!fi.IsEof() && fi.IsOK())
	fi.Get(); // do something with it...

If you want to read an *.ini file you may use LoadIniFile (see help).
