L_VecGetMarker

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecGetMarker(pVector, pMarker)

const pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORMARKER pMarker;	/* pointer to a structure */

Gets the current marker settings.

Parameter	Description
pVector	Pointer to a vector handle.
pMarker	Pointer to a VECTORMARKER structure to be updated with the current marker settings.

Returns

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

Comments

The marker is used to indicate those objects within the vector handle that are selected.

For more information on available marker settings, refer to the VECTORMARKER structure.

To modify the marker settings, get the current settings by calling L_VecGetMarker, set the new settings in the structure pointed to by pMarker, and call L_VecSetMarker.
