[/* The _GL_ASYNC_SAFE marker should be attached to functions that are
signal handlers (for signals other than SIGABRT, SIGPIPE) or can be
invoked from such signal handlers. Such functions have some restrictions:
* All functions that it calls should be marked _GL_ASYNC_SAFE as well,
or should be listed as async-signal-safe in POSIX
<http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_04>
section 2.4.3. Note that malloc(), sprintf(), and fwrite(), in
particular, are NOT async-signal-safe.
* All memory locations (variables and struct fields) that these functions
access must be marked 'volatile'. This holds for both read and write
accesses. Otherwise the compiler might optimize away stores to and
reads from such locations that occur in the program, depending on its
data flow analysis. For example, when the program contains a loop
that is intended to inspect a variable set from within a signal handler
while (!signal_occurred)
;
the compiler is allowed to transform this into an endless loop if the
variable 'signal_occurred' is not declared 'volatile'.
Additionally, recall that:
* A signal handler should not modify errno (except if it is a handler
for a fatal signal and ends by raising the same signal again, thus
provoking the termination of the process). If it invokes a function
that may clobber errno, it needs to save and restore the value of
errno. */
