- * \brief Copy the contents from another buffer
- * \param[in] src FrameBuffer to copy
- *
- * Copy the buffer contents and metadata from \a src to this buffer. The
- * destination FrameBuffer shall have the same number of planes as the source
- * buffer, and each destination plane shall be larger than or equal to the
- * corresponding source plane.
- *
- * The complete metadata of the source buffer is copied to the destination
- * buffer. If an error occurs during the copy, the destination buffer's metadata
- * status is set to FrameMetadata::FrameError, and other metadata fields are not
- * modified.
- *
- * The operation is performed using memcpy() so is very slow, users needs to
- * consider this before copying buffers.
- *
- * \return 0 on success or a negative error code otherwise
