TODO

Declaration Syntax

Visual Basic

Visual C++

public static void SetStreamFunctionRead(
	PlStreamType streamType,
	DelegateStreamReadFunction function
)

Public Shared Sub SetStreamFunctionRead ( 
	streamType As PlStreamType,
	function As DelegateStreamReadFunction
)

public:
static void SetStreamFunctionRead(
	PlStreamType streamType, 
	DelegateStreamReadFunction^ function
)

static member SetStreamFunctionRead : 
        streamType : PlStreamType * 
        function : DelegateStreamReadFunction -> unit

Parameters

streamType (PlStreamType): Determine which stream to use PlStreamType

function (DelegateStreamReadFunction): A DelegateStreamReadFunction

Examples

	Copy

Copy

static internal long Sread(IntPtr handle, IntPtr buffer, long buffersize)
{
    const string s = ValidationStringRead + "\n";
    byte[] array = System.Text.Encoding.Unicode.GetBytes(s);
    System.Runtime.InteropServices.Marshal.Copy(array, 0, buffer, array.Length);
    return array.Length;
}


[TestMethod]
public void StreamRead()
{
    var rf = new DelegateStreamReadFunction(Sread);
    PlEngine.SetStreamFunctionRead(PlStreamType.Input, rf);
    // NOTE: read/1 needs a dot ('.') at the end
    PlQuery.PlCall("assert( (test_read(A) :- read(A)) )");
    PlTerm t = PlQuery.PlCallQuery("test_read(A)");
    Assert.AreEqual(ValidationStringRead, t.ToString()+".");
}
