PROGRESSCALLBACK2

#include "ltdoc2.h"

L_BOOL pEXT_CALLBACK YourFunction(pProgressData, pUserData)

pPROGRESSDATA2 pProgressData;	/* pointer to PROGRESSDATA2 structure */
L_VOID * pUserData;	/* pointer to additional parameters */

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

Parameter	Description
pProgressData	Pointer to a PROGRESSDATA2 structure that contains progress data for the current process.
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 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

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments
