RPC_X_NULL_REF_POINTER - 1780 (0x6F4)
A null reference pointer was passed to the stub.
Updated: Feb 21, 2026
Technical Meaning
The error code RPC_X_NULL_REF_POINTER indicates that a null reference pointer was passed to the stub. This is a specific technical mechanism where an invalid or uninitialized pointer value has been used in a context expecting a valid pointer.
Error Details
This error typically occurs during Remote Procedure Call (RPC) operations, where a null pointer is passed as an argument to a function that expects a non-null reference. The stub is responsible for handling the call and encountering this condition results in the generation of the RPC_X_NULL_REF_POINTER error.
Usage Context
The context in which this error occurs can vary depending on the specific RPC operation being performed. It often arises when an application or service attempts to invoke a remote procedure with invalid parameters, particularly those involving pointers that should not be null.
Developer Interpretation
Developers encountering this error should consider it as an indication of a programming issue where a pointer was expected but was not properly initialized before being passed to the RPC stub. This could be due to a variety of reasons such as incorrect parameter handling, uninitialized variables, or improper function calls.
Related Errors
RPC_X_BAD_STUB_DATA: Indicates invalid data in the stub.RPC_X_WRONG_STUB_VERSION: Occurs when the wrong version of the RPC stub is used.
FAQ
Q: What does the error code 1780 (0x6F4) signify?
A: The error signifies that a null reference pointer was passed to the RPC stub, indicating an invalid parameter or uninitialized variable in the context of an RPC operation.
Q: How can I prevent this error from occurring?
A: Ensure all pointers used in RPC calls are properly initialized and validated before being passed as arguments. Review function parameters for correctness and ensure that any pointer values are not null when required.
Summary
The RPC_X_NULL_REF_POINTER error is a specific technical mechanism indicating an invalid parameter, specifically a null reference pointer, was passed to the RPC stub during an operation. Developers should focus on proper initialization and validation of pointers in their code to avoid this issue.
