FAQ and INFOLarry A. Walker & Co. B+Tree Index Source:::::What is this product?This product is C language source code for a library of B+Tree functions.  You integrate the functions into your program.  Itis intended for use by software engineers who are building systemsrequiring a robust indexing system.Distributed with the B+Tree :A tree debugger and various list and test programs.A set of double link list functions which are not requiredin the B+Tree.  In order to use this product you would need to know the Cprogramming language, have a working knowledge of makefiles and such, and understand the general concept of a B+Tree index system.  This product is the C version of an earlier product,  "B+Tree in C++"This product is released in Dec 2002 under the GNU Public License.See license agreement.The product is downloaded as a Unix tar file; gzip compressed, ornot compressed.The product has been built for a number of Unix OS.
