Re: libssh multi-threading issue

[Anne Zhang <meantobe997@xxxxxxxxxxx>]

Hi Mike,

Thanks for the reply. Unfortunately, I am only implementing an .so file and
have no access to the main program. I understand ssh_init() would solve the
problem but my library is being called within a thread and I cannot change
what's in the main/original thread.

Look forward to additional input.

Thanks,

Anne
