L_UINT uFlags; |
flags that determine function behavior |
Gets a copy of the last markers set with L_SetMarkers.
Parameter |
Description |
phMarkers |
Pointer to a variable to be updated with a handle to a copy of the collection of markers last set with L_SetMarkers. This cannot be NULL. |
uFlags |
Reserved for future use. Pass 0. |
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 L_SetMarkers.
When the marker collection handle is no longer needed, use L_FreeMarkers function to free it.
When calling L_GetMarkers, the phMarkers parameter cannot be NULL. However, if no markers have been set using L_SetMarkers, the phMarkers parameter will be updated with NULL when the function returns.
