* isc_mem_putanddetach() is a convienence function for use where you
* have a structure with an attached memory context.
*
* Given:
*
* struct {
* ...
* isc_mem_t *mctx;
* ...
* } *ptr;
*
* isc_mem_t *mctx;
*
* isc_mem_putanddetach(&ptr->mctx, ptr, sizeof(*ptr));
*
* is the equivalent of:
*
* mctx = NULL;
* isc_mem_attach(ptr->mctx, &mctx);
* isc_mem_detach(&ptr->mctx);
* isc_mem_put(mctx, ptr, sizeof(*ptr));
* isc_mem_detach(&mctx);
