This project offers various tree implementations starting with the red black tree implementation.
The base for the project are provided by the libtree project on github which is a C implementation for various tree data structures. The code can be compiled on IBM i with the ILE C compiler with almost no changes to the code.
This project contains prototypes for the C functions. On top of that the project has wrapper modules for the red black tree C implementation to make it easier to use the C functions. The wrapper modules support integer and strings as keys. The values are added untyped (via pointer).
The string module supports strings as keys. The value of the entry can be anything as it is passed as a pointer. The module provides two procedures for key comparison.
As the name already points out, the ignore case variant of the comparison procedure evaluates "My Key" and "my key" as equal.
This software has no further dependencies. It comes with all necessary files.
For standard installation the setup script can be executed as is. This will
build the service program in the library OSSILE. If you want to build the
service program in any other library export the library name in the variable
TARGET_LIB like this
before executing the setup script.
For automatically copying the copybook to a directory in the IFS export
INCDIR like this
before executing the setup script. The directory which is stated in the export should exist before executing the script.
Take a look in the example section to see how to use the procedures.
