Gets a copy of the last markers set with LMarker::SetAsGlobalMarkers.
#include "ltwrappr.h"
virtual L_INT LMarker::GetGlobalMarkers(uFlags)
Reserved for future use. Pass 0.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
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.
Win32, x64.
