Namespace: BCL
Assembly: xprbdn (in xprbdn.dll) Version: 4.8.14.0

Syntax

Copy

public delegate void XPRBDelVarCallback(
	IntPtr prob,
	Object vContext,
	IntPtr XBvar,
	IntPtr link
)

Public Delegate Sub XPRBDelVarCallback ( 
	prob As IntPtr,
	vContext As Object,
	XBvar As IntPtr,
	link As IntPtr
)

Parameters

prob: Type: SystemIntPtr
The IntPtr prob object of the current BCL problem. This will receive the BCL prob pointer.
vContext: Type: SystemObject
The user object as set when creating the callback using AddDelVarCallback.
XBvar: Type: SystemIntPtr
IntPtr reference to a BCL variable.
link: Type: SystemIntPtr
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);
