ERROR_BAD_COMPRESSION_BUFFER - 605 (0x25D)

Technical Meaning

The ERROR_BAD_COMPRESSION_BUFFER error code indicates that a compression operation encountered an issue with the buffer provided. Specifically, the data within the buffer is not in a format expected by the compression algorithm.

Error Details

This error typically occurs when attempting to compress or decompress data using Windows API functions such as CompressFile, DecompressFile, or related functions from the WinInet library. The error suggests that the input buffer contains invalid or corrupted data, which prevents the compression process from proceeding correctly.

Usage Context

The context in which this error might occur includes scenarios where:

• A file is being compressed and the provided buffer does not contain valid data to be processed by the compression algorithm.
• Data is being decompressed but the input buffer contains corrupted or improperly formatted data, leading to an invalid state during the decompression process.

Developer Interpretation

Developers should ensure that any buffers used for compression or decompression operations are properly initialized and contain valid data. This includes verifying the integrity of the source data before attempting to compress it and ensuring that the buffer size is adequate to hold the compressed data without truncation.

Related Errors

• ERROR_INVALID_PARAMETER (1208, 0x4B8): Indicates that one or more parameters passed to a function are invalid. This error might be encountered if the buffer size is incorrect for the operation being performed.
• ERROR_COMPRESSION_FAILED (936, 0x398): Occurs when an attempt to compress data fails due to issues unrelated to the buffer format but may coexist with ERROR_BAD_COMPRESSION_BUFFER in certain scenarios.

FAQ

Q: What does ERROR_BAD_COMPRESSION_BUFFER mean?

A: It indicates that a compression operation encountered ill-formed data within the provided buffer. Ensure the buffer contains valid and properly formatted data before attempting to compress or decompress it.

Q: How can I resolve this error?

A: Verify that the input buffer is correctly initialized with valid data and that its size is appropriate for the operation being performed. Correct any issues with the buffer content or size, then retry the compression or decompression operation.

Summary

The ERROR_BAD_COMPRESSION_BUFFER error code highlights an issue with the format of data within a buffer used in compression operations. Developers should ensure that buffers are properly initialized and contain valid data to avoid this error.
