Error Details
- Error Name: RPC_S_NO_CALL_ACTIVE
- Numeric Code: 1725 (0x6BD)
- Short Description: There are no remote procedure calls active on this thread.
This error typically occurs when a function or operation that expects an active RPC call is invoked, but none exists. It can be encountered in various scenarios where RPC-based operations are expected to be ongoing.
Usage Context
The context in which RPC_S_NO_CALL_ACTIVE is used depends on the specific application and its interaction with remote procedure calls (RPC). Common usage includes:
- Initialization: Ensuring that an RPC call has been established before attempting to use it.
- Finalization: Checking if all RPC calls have completed or are no longer active before performing cleanup operations.
Developer Interpretation
Developers should interpret this error as a signal that the current thread does not have any active RPC calls. This can be useful for debugging and ensuring proper synchronization between threads in applications that rely on RPC communication.
Related Errors
- RPC_S_CALL_ACTIVE: Indicates an attempt to perform an operation while an RPC call is already active.
- RPC_S_CALL_FAILED: Indicates a failure in the current RPC call, which might not be directly related but can occur in similar contexts.
