Given the following scenario:
1. an interpreter instance is created with RexxCreateInterpreter(),
loading a native library "ABC" via the options argument, all
loaded routines will be visible from thereon to every program that
gets called
2. using CallProgram() for some program "d.rex" which loads a library
"DEF", then ends
3. using CallProgram() for some program "g.rex" which loads a library
"GHI", then ends
4. using CallProgram() for some program "j.rex" which loads a library
"JKL", then continues to run and via native code there will be
callbacks to ooRexx that occur via another CallProgram() from
native code
Questions:
1. in 3. above: would all public routines and public classes that got
loaded in 2. (e.g. via a "::requires DEF") be visible in 3. ?
2. would the program in 4. see all public routines and public classes
of the previously loaded libraries DEF and GHI ?
3. for a callback from native code to Rexx in 4. above, which public
routines/classes would be available to the callback, how would one
be able to use (actually to fetch a reference to) those available
public routines/classes?
1. Scenario: the only thing available to native code currently
is a reference to an ooRexx object that got stored in the
native interface layer in an earlier call from a running
Rexx program.
2. It would be possible to fetch a reference to routine's
package object and store that with the ooRexx object and
then on callbacks use that. Is this advisable?
4. if this is possible at all: how could one determine from native
code whether a given library is loaded and if so, how could one
get access to its routines and classes?
