Detailed Description

Point Shape Buffer accessor functions.

These functions provide access to the shape buffer. Consult the extended shapefile format document for the buffer layout. When reading a point shape buffer you should first create the appropriate shape buffer, get the geometry, get the point, and any z or m values. To write a point create a row buffer, create a shape buffer, set up the shape buffer, get the point, assign the coordinates to the point, assign z and m values if present, set the geometry and insert the row.
