Swi-cs-pl - A CSharp class library to connect .NET languages with SWI-Prolog SetStreamFunctionWrite Method (streamType, function)
SwiPlCs interface ► SbsSW.SwiPlCs ► PlEngine ► SetStreamFunctionWrite(PlStreamType, DelegateStreamWriteFunction)
This is a primitive approach to enter the output from a stream.
Declaration Syntax
C# Visual Basic Visual C++ F# 
public static void SetStreamFunctionWrite(
	PlStreamType streamType,
	DelegateStreamWriteFunction function
)
Public Shared Sub SetStreamFunctionWrite ( 
	streamType As PlStreamType,
	function As DelegateStreamWriteFunction
)
public:
static void SetStreamFunctionWrite(
	PlStreamType streamType, 
	DelegateStreamWriteFunction^ function
)
static member SetStreamFunctionWrite : 
        streamType : PlStreamType * 
        function : DelegateStreamWriteFunction -> unit
Parameters
streamType (PlStreamType)
Determine which stream to use PlStreamType
function (DelegateStreamWriteFunction)
A DelegateStreamWriteFunction
Examples
  Copy imageCopy 
static string _testString;

static long Swrite(IntPtr handle, string buffer, long buffersize)
{
    string s = buffer.Substring(0, (int)buffersize);
    _testString = s;
    return buffersize;
}

[TestMethod]
public void StreamWrite()
{
    // NOTE: the Swrite function is only called if you flush the output or send a newline character
    const string validationString = "Hello .net world ����"; // The last 4 characters are German umlauts.
    PlQuery.PlCall("assert( (test_write :- writeln('" + validationString + "'), flush_output) )");
    var wf = new DelegateStreamWriteFunction(Swrite);
    PlEngine.SetStreamFunctionWrite(PlStreamType.Output, wf);
    PlQuery.PlCall("test_write");
    Assert.AreEqual(validationString+"\r\n", _testString);
}
