Reply Fields

response_type
The type of this reply, in this case XCB_GLX_GET_CONVOLUTION_PARAMETERIV. 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).
n
TODO: NOT YET DOCUMENTED.
datum
TODO: NOT YET DOCUMENTED.

Return Value

Returns an xcb_glx_get_convolution_parameteriv_cookie_t. Errors have to be handled when calling the reply function xcb_glx_get_convolution_parameteriv_reply.

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

Errors

This request does never generate any errors.
