REPLY FIELDS

response_type
    The type of this reply, in this case XCB_GLX_GET_CONVOLUTION_FILTER. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.

sequence
    The sequence number of the last request processed by the X11 server.

length
    The length of the reply, in words (a word is 4 bytes).

width
    TODO: NOT YET DOCUMENTED.

height

DESCRIPTION

RETURN VALUE
Returns an xcb_glx_get_convolution_filter_cookie_t. Errors have to be handled when calling the reply function xcb_glx_get_convolution_filter_reply.

If you want to handle errors in the event loop instead, use xcb_glx_get_convolution_filter_unchecked. See xcb-requests(3) for details.

ERRORS
This request does never generate any errors.
