Technical Meaning
The RPC_X_BAD_STUB_DATA error code indicates that the stub received bad data during a Remote Procedure Call (RPC) operation. This typically suggests an issue with the input parameters or data being passed to the RPC stub, which is responsible for marshaling and unmarshaling data between the client and server.
Error Details
- Error Name:
RPC_X_BAD_STUB_DATA - Numeric Code: 1783 (0x6F7)
- Short Description: The stub received bad data.
This error is specific to RPC operations and indicates that the data passed to or from the stub was not in a valid format, leading to an incorrect state or operation failure.
Usage Context
The RPC_X_BAD_STUB_DATA error can occur in various scenarios where RPC calls are made. Common contexts include network communication between client and server applications, where data integrity and correctness are critical for successful operations.
Developer Interpretation
When encountering the RPC_X_BAD_STUB_DATA error, developers should consider the following aspects:
- Parameter Validation: Ensure that all input parameters passed to RPC functions are valid and correctly formatted. Invalid or corrupted data can lead to this error.
- Data Integrity: Verify that the data being transmitted is intact and not corrupted during transmission. This includes checking for any issues in serialization or deserialization processes.
- Context Dependency: The context in which the RPC call is made can influence whether this error occurs. For example, incorrect object types or exceeding limits might trigger this error.
