#include "ltvkrn.h"

L_LTVKRN_API L_BOOL L_VecIsLocked(pVector)

Determines whether or not the specified vector handle is locked.

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

Returns

Value Meaning
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.
