Functions Callable From Deferred Tasks
Table C-3 lists Open Transport functions that you can call from a deferred task and specifies whether the call can only be made with a provider in asynchronous mode.
In general, all endpoint calls can be made asynchronously from a deferred task, with the following limitation.
- Note
- Some functions listed in Table C-3 are not documented in this manual because they are specific to Open Transport protocol and device drivers. They are listed here to provide a complete reference
