ptv provides functions that apply set operations on collections of prefix tables of addresses with arbitrary size. In particular, ptv supports ipv4 and ipv6 prefix table set operations. Glenn Fowler Information and Software Systems Research [email protected] This directory contains ptvsa, the standalone code for ptv. ptvsa requires the ast standalone astsa source package. Read this package and astsa in the same directory and run this to build libptvsa.a: make -f ptvsa.omk and this to build the test harness and test the library: make -f ptvsa.omk test You may have to do some /bin/make plumbing on *.omk to get it to work on your system. The library interface is implemented in libptvsa.a; include ptv.h in your source and link your a.out with libptvsa.a. ptvsa.omk (for old make) pulls in standalone headers and source. 'testptv --man' lists the test harness man page on the standard error. ptv.3 is the api man page. See testptv.c for example api usage. ptvsa is a subset of the { ast-base ast-dss } packages at http://www.research.att.com/sw/download/
