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

DESCRIPTION
RETURN VALUE
Returns an xcb_glx_get_histogram_parameterfv_cookie_t. Errors have to
be handled when calling the reply function xcb_glx_get_histogram_param-
eterfv_reply.
If you want to handle errors in the event loop instead, use
xcb_glx_get_histogram_parameterfv_unchecked. See xcb-requests(3) for
details.
ERRORS
This request does never generate any errors.
