Namespace:   BCL
Assembly:  xprbdn (in xprbdn.dll) Version: 44.01.04
Syntax
C# 
[ObsoleteAttribute("Deprecated since version 41, will be removed in the future.", 
	false)]
public delegate void XPRBDelVarCallback(
	IntPtr prob,
	Object vContext,
	IntPtr XBvar,
	IntPtr link
)
VB 
<ObsoleteAttribute("Deprecated since version 41, will be removed in the future.", 
	false)>
Public Delegate Sub XPRBDelVarCallback ( 
	prob As IntPtr,
	vContext As Object,
	XBvar As IntPtr,
	link As IntPtr
)

Parameters

prob
Type:  System.IntPtr
The IntPtr prob object of the current BCL problem. This will receive the BCL prob pointer.
vContext
Type:  System.Object
The user object as set when creating the callback using AddDelVarCallback.
XBvar
Type:  System.IntPtr
IntPtr reference to a BCL variable.
link
Type:  System.IntPtr
IntPtr to an interface object.
Remarks
This defines a callback that is called at the deletion of any variable that is used in an interface to an external program, (that means, if the interface pointer of the variable is different from IntPtr.Zero).
Examples
XPRBprob prob = new XPRBprob("NewProb"); object userData = IntPtr.Zero; XPRBDelVarCallback dvarCB = new XPRBDelVarCallback(delvar_cb_method); prob.AddDelVarCallback(dvarCB, userData);
