The decision to use fifo synchronous is left up to the server. - mailbox: Tells the server to use a mailbox present mode. - present_mode: Must be one of wl_eglstream_controller_present_mode. Tells the server the desired present mode that should be used. - fifo_length: Only valid when the present_mode attrib is provided and its value is specified as fifo. Tells the server the desired fifo length to be used when the desired present_mode is fifo. Creates the corresponding server side EGLStream from the given wl_buffer and attaches a consumer to it. Creates the corresponding server side EGLStream from the given wl_buffer and attaches a consumer to it using the given attributes. It contains key-value pairs compatible with intptr_t type. A key must be one of wl_eglstream_controller_attrib enumeration values. What a value represents is attribute-specific.
