Problem is:  I have a program that spawns another (Non_Blocking_Spawn in Gn=
at.Expect) and communicates with it by sending it variable length strings p=
receeding by a token telling the son what to do with it.  I would like they=
 did it by exchanging objects through the 'Output and 'Input atribute.

Problem is: Non_Blocking_Spawn works with Process_Descriptors from them you=
 can get a File_Descriptor (from Gnat.Os_Lib.File_Descriptor) but I have be=
en unable to find a way for mapping a Stream on a File_Descriptor.

Any ideas?

PS: I could resort to forget about Objects and Streams and just parse input=
 in son, in fact that is what I did in a previous version but that is sooo =
crude and unelegant.  That is why I would like to use Objects and Streamas.
