LMarker::GetGlobalMarkers

#include "ltwrappr.h"

virtual L_INT LMarker::GetGlobalMarkers(uFlags)

L_UINT uFlags;

/* reserved flags */

Gets a copy of the last markers set with LMarker::SetAsGlobalMarkers.

Parameter	Description
uFlags	Reserved for future use. Pass 0.

Returns

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

Comments

Since you have a copy, anything you do with the handle will not modify the markers, which can be saved by calling a Save function. To modify the markers being saved, call LMarker::SetAsGlobalMarkers.

When the marker collection handle is no longer needed, use LMarker::Free function to free it.

When calling LMarker::GetGlobalMarkers, the markers object cannot be NULL. However, if no markers have been set using LMarker::SetAsGlobalMarkers, the markers object will be updated with NULL when the function returns.
