I have a problem with my code but first a short description:
1. I have one signal call SIGUSR1
2. In the signal I try to use nanosleep and now:
When I put kill -SIGUSR1 pid --> sometimes works fine, sometimes returns me an error with ,,Interrupt system call", sometimes I got error with "Success". Why? What mistake did I make? How to improve that?
My code:

Hi Everybody,
I have gone through man of sigwait and new to UNIX signals. Could anyone explain me about the following lines mentioned in sigwait man help ?
"The selection of a signal in set is independent of the signal
mask of the calling thread or LWP. This means a thread or
LWP can ... (1 Reply)
Hello,
Can anyone, please, guide me on the use of nanosleep. I'm learning threads. I want to introduce a delay (not nested for loops, something more customizable). Nanosleep looked useful (or any other form of customizable and easy-to-use delay). Sleep is too long. :) (2 Replies)
Hi,
Ho do I differentiate system call from library call?
for example if I am using chmod , how do I find out if it is a system call or library call?
Thanks

Hi,
I have encountered the following problem on Solaris 10:
I have a thread that is asleep on nanosleep (set to 24 hours).
Something that happens on another thread, causes the nanosleep to exit, even though the time has not elapsed.
The returned value is 0 (so it doesn't look like it... (1 Reply)
Hi,
I have a daq program that runs in an infinite loop until it receives SIGINT. A handler catches the signal and sets a flag to stop the while loop. After the loop some things have to be cleaned up.
The problem is that I want my main while loop to wait until the next full second begins, to... (2 Replies)

Application runs on both solaris 6 and 10.
solaris 6 having only posix4.so library, solaris 10 having libposix4.so and librt.so
Can we link application to lposix4 instead of lrt for nanosleep, sothat application will run in both machines? (2 Replies)

kill
KILL(1) BSD General Commands Manual KILL(1)NAME
kill -- terminate or signal a process
SYNOPSIS
kill [-s signal_name] pid ...
kill -l [exit_status]
kill -signal_name pid ...
kill -signal_number pid ...
DESCRIPTION
The kill utility sends a signal to the process(es) specified by the pid operand(s).
Only the super-user may send signals to other users' processes.
The options are as follows:
-s signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-l [exit_status]
Display the name of the signal corresponding to exit_status. exit_status may be the exit status of a command killed by a signal (see
the special sh(1) parameter '?') or a signal number.
If no operand is given, display the names of all the signals.
-signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-signal_number
A non-negative decimal integer, specifying the signal to be sent instead of the default TERM.
The following pids have special meanings:
-1 If superuser, broadcast the signal to all processes; otherwise broadcast to all processes belonging to the user.
0 Broadcast the signal to all processes in the current process group belonging to the user.
Some of the more commonly used signals:
1 HUP (hang up)
2 INT (interrupt)
3 QUIT (quit)
6 ABRT (abort)
9 KILL (non-catchable, non-ignorable kill)
14 ALRM (alarm clock)
15 TERM (software termination signal)
kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill argu-
ments. See csh(1) for details.
SEE ALSO csh(1), pgrep(1), pkill(1), ps(1), kill(2), sigaction(2), signal(7)STANDARDS
The kill function is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A kill command appeared in Version 6 AT&T UNIX.
