31 * @file ownership_transfer.c
33 * From the EXT_image_dma_buf_import spec:
35 * "3. Does ownership of the file descriptor pass to the EGL library?
37 * ANSWER: No, EGL does not take ownership of the file descriptors. It is the
38 * responsibility of the application to close the file descriptors on success
39 * and failure.
42 * Here one checks that the creator of the buffer can drop its reference once
43 * it has given the buffer to EGL, i.e., after calling 'eglCreateImageKHR()'.
