ERROR_DISCARDED - 157 (0x9D)

Technical Meaning

The ERROR_DISCARDED error code indicates that a requested operation on a segment of data or memory could not be completed because the segment has already been discarded. This typically means that the segment is no longer valid and cannot be accessed for operations such as locking.

Error Details

This error is specific to scenarios where an attempt is made to lock a segment of data, but the segment has already been marked as discarded by the system or application. Locking a discarded segment would result in undefined behavior, hence this error is returned to prevent potential issues.

Usage Context

ERROR_DISCARDED can occur in various contexts where segments of memory or data are managed and potentially discarded. Common scenarios include:

• Memory management operations
• File system operations involving segments of files or directories
• Data processing pipelines that discard certain segments based on specific criteria

Developer Interpretation

When encountering ERROR_DISCARDED, developers should understand that the segment in question is no longer valid and cannot be used for further operations. This error suggests that the operation was attempted on a segment that has been discarded, possibly due to changes in state or conditions outside the current context.

Related Errors

• ERROR_INVALID_PARAMETER (0x57): Occurs when an invalid parameter is passed to a function.
• ERROR_HANDLE_EOF (0x8F): Indicates end of file has been reached, which might be related if the segment was part of a file or stream.
• ERROR_NOT_ENOUGH_MEMORY (0x0A): Suggests that memory allocation failed, possibly leading to segments being discarded.

FAQ

Q: What does ERROR_DISCARDED mean?

A: It indicates that an attempt was made to lock a segment of data or memory that has already been discarded and is no longer valid for such operations.

Q: How can I avoid this error?

A: Ensure that the segments you are working with have not been discarded before attempting to perform operations on them. Verify the state of the segments prior to performing locking operations.

Summary

ERROR_DISCARDED is a specific error code indicating an attempt to lock a segment of data or memory that has already been discarded. Developers should handle this error by ensuring that all segments are valid and not discarded before attempting such operations.
