ERROR_SHUTDOWN_IS_SCHEDULED - 1190 (0x4A6)

Technical Meaning

The ERROR_SHUTDOWN_IS_SCHEDULED error code, with the numeric value of 1190 and the hexadecimal representation 0x4A6, is returned when a system shutdown has already been scheduled. This indicates that an operation attempting to initiate a shutdown or perform actions related to the shutdown process will fail because the system is in a state where it is preparing for or undergoing a shutdown.

Error Details

This error code is specific to scenarios involving system shutdown operations. It is commonly encountered when applications attempt to schedule a shutdown, or when certain system processes are initiated that conflict with an already scheduled shutdown event.

Usage Context

The ERROR_SHUTDOWN_IS_SCHEDULED error can be returned in various contexts where the system is preparing for or undergoing a shutdown process. This includes but is not limited to:

• Scheduling a system shutdown through API calls such as InitiateSystemShutdownEx.
• Performing operations that are incompatible with an ongoing shutdown, such as writing to certain system files or directories.

Developer Interpretation

When this error code is returned, developers should interpret it as indicating that the operation they attempted cannot proceed because a system shutdown has already been initiated. This may require the application to handle the situation gracefully by either terminating operations or waiting for the shutdown process to complete before attempting further actions.

Related Errors

• ERROR_SHUTDOWN_IN_PROGRESS (0x4A7): Indicates that the system is currently in the process of shutting down, which might be a more specific state than what ERROR_SHUTDOWN_IS_SCHEDULED indicates if the shutdown has not yet been initiated but is expected to occur shortly.
• ERROR_INVALID_PARAMETER (0x57): If an invalid parameter was passed during a shutdown operation, this error code may also be returned, indicating that the parameters provided were incorrect or inappropriate for the current state of the system.

Q: How should I handle this error in my application?

A: You should ensure your application can gracefully handle situations where a shutdown is imminent or in progress. This may involve terminating operations, saving state information, or waiting for the system to complete its shutdown process before proceeding with further actions.

Summary

The ERROR_SHUTDOWN_IS_SCHEDULED error code provides critical information about the current state of the system regarding shutdown operations. Developers should be aware of this error and handle it appropriately in their applications to ensure smooth operation during system shutdowns.
