Handles common case of allocating & copying string to temporary buffer (cherry picked from xorg/lib/libxkbfile@8a91517ca6ea77633476595b0eb5b213357c60e5) Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Part-of: <https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/1821>
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.
