ArgEnv Version 1.0.3 Ronny Wichers Schreur ronny@cs.kun.nl The ArgEnv package provides a Clean interface to the command line arguments and the environment variables. This is the README for the Unix version. The Unix version has been tested on Solaris 5.5 and Clean 1.1 & 1.3, but it should work with all Unix versions with Clean 1.1 or better. To use the package with Clean version 1.1 you will have to make a few changes, which are documented in the source. FILES README This file CHANGES.txt Changes history ArgEnv.dcl Definition of the interface ArgEnv.icl Implementation of the interface ArgEnvC.c Implementation of the C side of the interface Makefile Makefile for the ArgEnv interface and the example program printenv.icl An example program that prints the value of an environment variable USAGE To use the ArgEnv interface you have to link the object module that is created from the module ArgEnvC.c. If you use clm you should specify this extra object file with the -l option: % clm -l ArgEnvC.o In the CleanIDE you can add this extra object file to the Object Modules section in the Options->Link Options dialogue. If you forget this, you will get the link error: Undefined first referenced symbol in file ArgEnvCopyCStringToCleanStringC ArgEnv.o ArgEnvGetEnvironmentVariableC ArgEnv.o ArgEnvGetCommandLineArgumentC ArgEnv.o ArgEnvGetCommandLineCountC ArgEnv.o BUGS There is no way to stop the Clean run-time system from interpreting some of the command-line arguments.
