Description
VECNextShape() is used to visit all entities in a vector layer in a manner analogous to the DBNextSeg() function.
Call Signature
int VECNextShape ( int/string filespec, int segment_num, int last_shape )
Return Value
int
The shape id of the next shape after the shape passed in or -1 when there are no more entities.
Arguments
int/string filespec:
This can either be the handle returned by DBOpen(), or the name of an open file.
int segment_num:
The vector layer (segment) number being accessed.
int last_shape:
The shape preceding the one to be returned. If this is -1, then the first shape will be returned.
