I'm no REAL ADMIN - but I have a FreeBSD server box for my home LAN:
Anyway : I was new to FreeBSD - and had just about set it up EXACTLY as wanted; after much tinkering! I was then trying to update my fstab to include my floppy drive. Unfortunately, I did the stupid thing of "echo"ing the details in, sorta like:
Hello all! Please help me with the following complex regexp which works in egrep:

Hi,
I am new registered user here in this UNIX forums.
I am a new system administrator for AIX 6.1. One of our servers performs poorly every time our application (FINACLE) runs many processes/instances. (see below for topas snapshot)
I use NMON or Topas to monitor the server utilization. I... (9 Replies)

pthread_detach
PTHREAD_DETACH(3) Linux Programmer's Manual PTHREAD_DETACH(3)NAME
pthread_detach - detach a thread
SYNOPSIS
#include <pthread.h>
int pthread_detach(pthread_t thread);
Compile and link with -pthread.
DESCRIPTION
The pthread_detach() function marks the thread identified by thread as detached. When a detached thread terminates, its resources are
automatically released back to the system without the need for another thread to join with the terminated thread.
Attempting to detach an already detached thread results in unspecified behavior.
RETURN VALUE
On success, pthread_detach() returns 0; on error, it returns an error number.
ERRORS
EINVAL thread is not a joinable thread.
ESRCH No thread with the ID thread could be found.
CONFORMING TO
POSIX.1-2001.
NOTES
Once a thread has been detached, it can't be joined with pthread_join(3) or be made joinable again.
A new thread can be created in a detached state using pthread_attr_setdetachstate(3) to set the detached attribute of the attr argument of
pthread_create(3).
The detached attribute merely determines the behavior of the system when the thread terminates; it does not prevent the thread from being
terminated if the process terminates using exit(3) (or equivalently, if the main thread returns).
Either pthread_join(3) or pthread_detach() should be called for each thread that an application creates, so that system resources for the
thread can be released. (But note that the resources of all threads are freed when the process terminates.)
EXAMPLE
The following statement detaches the calling thread:
pthread_detach(pthread_self());
