Using calloc() instead of malloc() as preventive measure, so there never can be any hidden bugs or leaks due uninitialized memory. The extra cost of using this compiler intrinsic should be practically impossible to measure - in many cases a good compiler can even deduce if certain areas really don't need to be zero'd (because they're written to right after allocation) and create more efficient machine code. The code pathes in question are pretty cold anyways, so it's probably not worth even thinking about potential extra runtime costs. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
The X server uses this directory to store the compiled version of the
current keymap and/or any scratch keymaps used by clients. The X server
or some other tool might destroy or replace the files in this directory,
so it is not a safe place to store compiled keymaps for long periods of
time. The default keymap for any server is usually stored in:
X<num>-default.xkm
where <num> is the display number of the server in question, which makes
it possible for several servers *on the same host* to share the same
directory.
Unless the X server is modified, sharing this directory between servers on
different hosts could cause problems.
