Hello,

it should not be a problem to have the code for ca_create_channel() and ca_get()
in two different C source files as long as they are linked toghether to one
program. Was that your question?

Of course you have to pass the chid handles from one file to the other. How do
you do that? Global variables? Check that the chid contains the value you
expect. Print it once after ca_create_channel and once before ca_get. (%p format
should do).

You cannot (easily) create channels and use them in a different THREAD. You have
to use ca_attach_context() for that.

Dirk

PS: A more detailed subject than "help" would be useful.
