moveTo()

TempFile::MoveStatus utils::TempFile::moveTo

(

const std::string &

destPath

)

Moves the temporary file to a new permanent location.

Attempts an atomic rename(). If that fails (e.g. cross-device move), it falls back to a manual copy followed by unlinking the source.

Note

IMPORTANT: On success, this TempFile object is invalidated (FD closed, path cleared). Ownership of the physical file is transferred to destPath. The file will NOT be deleted when this object is destroyed.

Parameters

destPath

Absolute path to the destination file.

Returns

MoveStatus indicating success or the specific type of failure.
