Description
Restore stack state saved with a previous call to onload_stackname_save(). All updates/changes to state of the current stack will be deleted and all state previously saved will be restored. To avoid unexpected results, the stack should be restored in the same thread as used to call onload_stackname_save().
Definition
int onload_stackname_restore (void)Formal Parameters
none
Return Value
0 on success
non-zero if an error occurs.
Notes
The API stackname save and restore functions provide flexibility when binding sockets to an Onload stack.
Using a combination of onload_set_stackname(), onload_stackname_save() and onload_stackname_restore(), the user is able to create default stack settings which apply to one or more sockets, save this state and then create changed stack settings which are applied to other sockets. The original default settings can then be restored to apply to subsequent sockets.
