I'm trying to do some cleanup (write open files) when Linux shuts down. I thought the right method would be to trap SIGTERM and do the necessary processing. Here's my sample code:
When I run this, and press Ctrl-C, it writes "got 2" to test.txt. However, if I logout/reboot, nothing is written to the file.

bsd_signal
BSD_SIGNAL(3) Linux Programmer's Manual BSD_SIGNAL(3)NAME
bsd_signal - signal handling with BSD semantics
SYNOPSIS
#define _XOPEN_SOURCE /* See feature_test_macros(7) */
#include <signal.h>
typedef void (*sighandler_t)(int);
sighandler_t bsd_signal(int signum, sighandler_t handler);
DESCRIPTION
The bsd_signal() function takes the same arguments, and performs the same task, as signal(2).
The difference between the two is that bsd_signal() is guaranteed to provide reliable signal semantics, that is: a) the disposition of the
signal is not reset to the default when the handler is invoked; b) delivery of further instances of the signal is blocked while the signal
handler is executing; and c) if the handler interrupts a blocking system call, then the system call is automatically restarted. A portable
application cannot rely on signal(2) to provide these guarantees.
RETURN VALUE
The bsd_signal() function returns the previous value of the signal handler, or SIG_ERR on error.
ERRORS
As for signal(2).
CONFORMING TO
4.2BSD, POSIX.1-2001. POSIX.1-2008 removes the specification of bsd_signal(), recommending the use of sigaction(2) instead.
NOTES
Use of bsd_signal() should be avoided; use sigaction(2) instead.
On modern Linux systems, bsd_signal() and signal(2) are equivalent. But on older systems, signal(2) provided unreliable signal semantics;
see signal(2) for details.
The use of sighandler_t is a GNU extension; this type is defined only if the _GNU_SOURCE feature test macro is defined.
