** FILE:           ecw_jni_config.c

** CREATED:        10 May 2004

** AUTHOR:         Mark Sheridan

** PURPOSE:        Java wrappers for JNI usage of the ECW config functions NCSecwSetConfig() && NCSecwGetConfig()

**                        For some bizarre reason those calls were implemented as var args, since Java doesnt have var_args

**                        it makes this code very verbose and prone to errors.
