L_LTFIL_API L_INT L_GetMarkers(phMarkers, uFlags)
Gets a copy of the last markers set with L_SetMarkers.
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.
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 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.
Required DLLs and Libraries
Win32, x64, Linux.
This example tells you whether you have set any markers or not
