L_VecSetLocked

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecSetLocked(pVector, bLock)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
L_BOOL bLock;	/* flag */

Locks or unlocks the specified vector handle. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
pVector	Pointer to a vector handle.
bLock	Flag that indicates whether to lock or unlock the specified vector handle. Possible values are:
	Value	Meaning
	TRUE	Lock the specified vector handle.
	FALSE	Unlock the specified vector handle.

Returns

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

Comments

Locking a vector handle has precedence over locking layers within the vector handle. Therefore, if a vector handle is locked, the layers within that vector handle cannot be edited, even if the layers are not locked.

To lock a layer, set the bLocked member of a VECTORLAYERDESC structure to TRUE and update the layer information using the L_VecSetLayer function.
