The timeout value is invalid.

Updated: Feb 21, 2026

Technical Meaning

The error RPC_S_INVALID_TIMEOUT indicates that a timeout value provided to an application programming interface (API) call is not valid. This can occur in scenarios where the API expects a specific range or format for the timeout parameter.

Error Details

This error code is returned by Remote Procedure Call (RPC) APIs when the specified timeout value does not meet the requirements of the function being called. The exact nature of the invalid timeout value can vary depending on the context in which it was provided, such as whether it falls outside a valid range or if it is not compatible with the API's expectations.

Usage Context

The RPC_S_INVALID_TIMEOUT error typically occurs when an application attempts to make an RPC call and specifies an inappropriate timeout value. This can happen due to incorrect parameter handling or misconfiguration of the application.

Developer Interpretation

Developers should ensure that any timeout values passed to RPC APIs are within the valid range specified by the API documentation. The specific range for a given API may vary, so it is crucial to consult the relevant documentation to understand the acceptable parameters.

Related Errors

  • RPC_S_CALL_FAILED (1720): Indicates that an RPC call failed due to other reasons not related to timeout values.
  • RPC_S_INVALID_BINDING (1713): Occurs when a binding handle is invalid, which might indirectly affect the handling of timeouts if bindings are involved in the API call.

FAQ

Q: What does the error RPC_S_INVALID_TIMEOUT mean?

A: It indicates that an invalid timeout value was provided to an RPC API function. Ensure that the timeout values meet the requirements specified by the API documentation.

Q: How can I resolve this issue?

A: Verify that the timeout values passed to the relevant RPC functions are within the valid range as documented in the API reference.

Summary

The RPC_S_INVALID_TIMEOUT error code signifies an invalid timeout value provided to a Remote Procedure Call (RPC) API. Developers should consult the specific API documentation for acceptable timeout ranges and ensure that their applications pass appropriate values to avoid this error.
