#include "ltdic.h"

L_BOOL pEXT_CALLBACK YourFunction(nIndex, nCount, pUserData)

Called for each image that is loaded using LDicomDS::GetImageList.


L_UINT32 nIndex

Zero-based index of the image to load.

L_UINT32 nCount

Total number of images to be loaded. This is the same value passed to the LDicomDS::GetImageList function.

L_VOID * pUserData

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 the LDicomDS::GetImageList function.)

Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.


Value Meaning
TRUE Continue loading.
FALSE Abort loading.


The LDicomDS::GetImageList function has two overload functions. GETIMAGECALLBACK is used with the version that has a callback.
