L_VecIsLocked

#include "lvkrn.h"

L_LVKRN_API L_BOOL L_VecIsLocked(pVector)

pointer to a vector handle

Determines whether or not the specified vector handle is locked.

Parameter	Description
pVector	Pointer to a vector handle.

Returns

TRUE	The specified vector handle is locked.
FALSE	The specified vector handle is not locked.

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.
