* Xlib.h: Fix macros imitating C functions.Dominik Muth2016-10-191-17/+17
| | | | | | | | | | | | | | | | | | The basic rule "put parantheses around macro parameters" should be observed where possible. Otherwise code like ConnectionNumber(foo = bar); fails to compile. (It obviously passes if ConnectionNumber is a C function.) There are several other macros amended for the same reason. This bug appeared while building http://ioccc.org/1993/cmills.c, so historically it was not present.

* XKB: fix XkbGetKeyboardByName with Xming serverOlivier Fourdan2016-10-191-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | XkbGetKeyboardByName relies on flags to read the data from the server. If the X server sends us the wrong flags or if a subreply is smaller than it should be, XkbGetKeyboardByName will not read all the available data and leave data in the buffer, which will cause the next _XReply() to fail with: [xcb] Extra reply data still left in queue [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. xcb_io.c:576: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed. Aborted Check if there is some extra data left at the end of XkbGetKeyboardByName() and discard that data if any is found.

* compose: fix the description of modifiers in compose sequencesRan Benita2016-10-191-2/+3
| | | | | | | | | | | | | | | | | | The Compose format has a feature which allows specifying certain modifiers must (or must not) be present with a given keysym in the sequence. The grammar in imLcPrs.c and the Compose man page both do not match what the code actually does (see the handling of the variables `modifier_mask` and `modifier` in parseline() in imLcPrs.c, which are eventually matched as `ev->state & modifier_mask == modifier`). Also explicitly list the accepted modifier names, since they are not standard (e.g. "Ctrl" instead of "Control").

* Fix validation of ctrls parameter to XkbGetPerClientControls()Alan Coopersmith2016-10-191-7/+4
| | | | | | | | | | | | | | | | | | | | Nothing in the XKB spec states that the memory pointed to by ctrls has to be initialized to any given value when passed to the function, only that it is set by the function to the values returned by the X server: http://www.x.org/releases/X11R7.7/doc/libX11/XKB/xkblib.html#The_Miscellaneous_Per_client_Controls The check for the incoming value seems to be copied from XkbSetPerClientControls without explanation. Instead change it to checking if ctrls is non-NULL, since there's no point asking the X server to return a value the caller won't even see. Found while investigating report from cppcheck-1.65: [nx-X11/lib/X11/XKB.c:699] -> [nx-X11/lib/X11/XKB.c:719]: (warning) Possible null pointer dereference: ctrls - otherwise it is redundant to check it against null.
