#include "l_bitmap.h"

L_INT EXT_CALLBACK YourFunction (hRgn, nLength, pUserData)

L_HRGN hRgn;	/* windows region */
L_INT nLength;	/* rake length */
L_VOID * pUserData;	/* pointer to additional parameters */

Handles each rake found by the L_RakeRemoveBitmap function.

Parameter	Description
hRgn	Windows region representing a rake to be removed. It is the programmers responsibility to delete this region, using L_FreeBitmapRgn when it is no longer needed.
nLength	Length in pixels of the rake.
pUserData	A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_RakeRemoveBitmap) function.
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

SUCCESS_REMOVE	Remove the rake.
SUCCESS_NOREMOVE	Do not remove the rake.
Otherwise	An error occurred. Refer to Return Codes.

Comments

The callback is called for each rake found. Return SUCCESS_REMOVE to have the rake removed. Return SUCCESS_NOREMOVE to leave the rake unchanged. Pass any other value to abort. This value will be the return value of the L_RakeRemoveBitmap function.
