PROGRESSCALLBACK2

#include "ltdoc2.h"

L_BOOL pEXT_CALLBACK YourFunction(pProgressData, pUserData)

Reports the progress of a specific operation and offers an opportunity to cancel. The address of this callback is passed as an argument to the L_Doc2SetProgressCB / L_Doc2SetProgressCBExt function.

Parameters

pPROGRESSDATA2 pProgressData

Pointer to a PROGRESSDATA2 structure containing progress data for the current process.

L_VOID * pUserData

A void pointer to access a variable or structure containing data that PROGRESSCALLBACK2 needs. This gives you a way to receive data indirectly from the function that uses PROGRESSCALLBACK2. (This is the same pointer that you pass in the pUserData parameter of the L_Doc2SetProgressCB function.)

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

Returns

Comments

PROGRESSCALLBACK2 is called periodically by the OCR engine.

To activate the progress callback function, call L_Doc2SetProgressCB / L_Doc2SetProgressCBExt.
