commit a89d3b4b42b16e13be0e6a9789b97e49e58601a4
Author: Chris Feng <address@hidden>
Commit: Chris Feng <address@hidden>
Data types related fixes
* el_client.el (xelb-imports, xelb-parse-import): Save imported libs in new
variable `xelb-imports'.
(xelb-node-type, xelb-parse-field, xelb-parse-list, xelb-parse-exprfield):
Use new function `xelb-node-type' to search defined types.
* xcb-composite.el:
* xcb-damage.el:
* xcb-glx.el:
* xcb-present.el:
* xcb-randr.el:
* xcb-xfixes.el:
* xcb-xinput.el:
* xcb-xv.el:
* xcb-xvmc.el:
Data types corrected.
* xcb-types.el: Add new 8 bytes data types `xcb:-u8' and `xcb:CARD64'.
Define `xcb:-fd' as an alias of `xcb:-i4'.
(xcb:-pack-u8, xcb:-pack-u8-lsb, xcb:-unpack-u8, xcb:-unpack-u8-lsb):
New functions for packing/unpacking 8 bytes data on 64/32-bit machines.
* Makefile: Eliminate a warning.
