Load shapefile partially

Dmontier Aragão
Hi all, i am facing a new problem using the SHAPELIB that i don't know to solve. I need to execute a dijkistra algoritms to a large number of points in a large map, i want to crop the map in order to reduce the time of the dijkstra problem.

I am looking for a method to load a shapefile partially, someone know a way for manage this.

Grateful in advance,
