Gets a copy of the last markers set with L_SetMarkers.
#include "l_bitmap.h"
L_LTFIL_API L_INT L_GetMarkers(phMarkers, uFlags)
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.
Win32, x64, Linux.
This example tells you whether you have set any markers or not

return nRet;
}

{
MessageBox(NULL, TEXT("You have set markers!"), TEXT("Info"), MB_OK);
L_FreeMarkers(hMarkers);
}
