Technical Meaning
The ERROR_INVALID_LEVEL error code indicates that a system call was made with an invalid level parameter. This typically occurs when the API function expects a specific level of detail or context, and the provided value does not match any valid levels.
Error Details
In Windows, system calls are often used to interact with various kernel objects and services. Each API function may require different levels of detail for its operation. For example, some functions might need detailed information about an object's state, while others might only require basic details. When the wrong level is provided, this error is generated.
Usage Context
This error can occur in various scenarios where a system call expects a specific level parameter but receives an invalid value. Common contexts include:
- File operations: Opening or querying file information with incorrect levels.
- Device management: Managing device drivers or hardware with inappropriate levels of detail.
- Security checks: Performing security-related operations with invalid access levels.
Developer Interpretation
