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

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);
