* Fix wrong Xfree in XListFonts failure pathJulien Cristau2017-03-261-2/+4
| | | | | | | | | | | | 'ch' gets moved inside the allocated buffer as we're looping through fonts, so keep a reference to the start of the buffer so we can pass that to Xfree in the failure case.

| | | | | | - Support for i18n in libNX_X11 is static only, has ever been. - Thus, the files XlcSL.[co], XlcDL.[co], XDefaultIMIF.[co], XDefaultOMIF.[co] and lcDynamic.[co] become obsolete.

* 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.
