Canon Edsdk | Documentation

The error codes are documented, but the recovery paths are not. What does EDS_ERR_TAKE_PICTURE_MIRROR_UP actually mean, and how does one clear it? If the camera disconnects mid-transfer, how should the developer clean up EdsImageRef handles? The documentation treats errors as terminal states rather than part of a robust recovery flow. Consequently, third-party applications are notoriously brittle compared to EOS Utility.

The documentation lists error codes like EDS_ERR_DEVICE_BUSY (0x00020003) or EDS_ERR_TAKE_PICTURE_MIRROR_UP_SEQUENCE (0x0002008F). But it rarely explains why they occur. Your best strategy: log every return value and consult the community for the obscure ones. canon edsdk documentation
