[zeromq-dev] question about czmq zctx_destroy

[Michel Pelletier]

This is nagging me in a minor way:

CZMQ_EXPORT zctx_t *
    zctx_new (void);

//  Destroy context and all sockets in it, replaces zmq_term
CZMQ_EXPORT void
    zctx_destroy (zctx_t **self_p);


Why does new return a pointer to a context, but destroy wants a pointer to
that pointer?  I'm trying to call this functions via an FFI interface, but
I can't pass the result of new to destroy and I don't have the equivalent
of the & operator in the FFI environment.

I've got a workaround, but is there a particular reason for this?
