[Shapelib] Example of how to create a shapefile

[Kleymeyer, Alan]

Thanks Frank.

After some search I finally found an example of someone using the
library so I added:

DBFCreate
DBFField(..,FTINTEGER, 11, 0)
DBFWriteIntegerAttribute(hDBFile, 0, 0, 0)

Which did the trick.

It would be nice if this type of example was included somewhere in the
sample code.  The sample code included in the library is all cmdline
driven
so I didn't find it helpful as a specific example of how to create a
shapefile.

Alan,

When I want to create a shapefile, but don't have any meaningful
attributes, I normally create a dbf file with one integer column that
I write an id to.   You can skim the dbfcreate and dbfadd programs
for a bit of an indication of how to use the dbf api.

Make sure you have one row in the dbf file for each shape object
created.

Best regards,
