CURPROC(9) BSD Kernel Developer's Manual CURPROC(9)NAME
curproc, curcpu, curlwp -- current process, processor, and LWP
SYNOPSIS
#include <sys/proc.h>
struct cpu_info *
curcpu(void);
struct proc *
curproc(void);
struct lwp *
curlwp(void);
DESCRIPTION
The following macros can be used to retrieve the current processor, process, and light-weight process (LWP), respectively:
1. The machine-dependent curcpu() macro returns a pointer to a cpu_info structure containing information of the CPU that this thread
is running on.
2. The machine-independent curproc() macro refers to a pointer to the process currently running on this CPU.
3. The curlwp() macro expands to a pointer to lwp structure, containing information about the current LWP. This macro is machine-
independent, but machine-dependent <machine/cpu.h> may redefine it.

_LWP_KILL(2) BSD System Calls Manual _LWP_KILL(2)NAME
_lwp_kill -- send a signal to a light-weight process
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <lwp.h>
int
_lwp_kill(lwpid_t lwp, int sig);
DESCRIPTION
_lwp_kill() sends the signal specified by sig to the light-weight process specified by lwp. If the sig argument is given as 0 (zero),
_lwp_kill will test for the existence of the target LWP, but will take no further action.
Job control signals and uncatchable signals can not be directed to a specific LWP: if posted with _lwp_kill, they will affect all LWPs in the
process.
Signals will be posted successfully to suspended LWPs, but will not be handled further until the LWP has been continued.
RETURN VALUES
A 0 value indicates that the call succeeded. A -1 return value indicates an error occurred and errno is set to indicate the reason.
ERRORS
[EINVAL] sig is not a valid signal number.
[ESRCH] No LWP can be found in the current process corresponding to that specified by lwp.
SEE ALSO _lwp_continue(2), _lwp_suspend(2), kill(2), sigaction(2), signal(7)HISTORY
The _lwp_kill() system call first appeared in NetBSD 5.0.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
