#include "ltwrappr.h"

L_UINT32 LVectorObject::GetDescription(pBuffer, uSize)

L_TCHAR * pBuffer;	/* pointer to a buffer */
L_UINT32 uSize;	/* size of pBuffer */

Retrieves the description string for the specified vector object.

Parameter	Description
pBuffer	Pointer to a buffer to be updated with the object description string.
uSize	Size of the buffer allocated for pBuffer.

Returns

If pBuffer is NULL, it will return the size of the buffer required for the description string. If pBuffer is not NULL, it will return the number of bytes actually written to the buffer.
