I am currently using SIGUSR1 and SIGUSR2 - but I need another one.
How can I do that?

Hi;
Is der ne to to use user defined functions for the values in awk
find $1 -type f -ls | nawk '{{print "|"$3"|"$5"|"$6"|"$8"|"$9"|"$10"|"} for(i=11;i<=NF;i++){printf("%s",$i)}}'
In above command i want to append some values returned by user functions on line.

thr_min_stack
thr_min_stack(3C) Standard C Library Functions thr_min_stack(3C)NAME
thr_min_stack - return the minimum-allowable size for a thread's stack
SYNOPSIS
cc -mt [ flag... ] file...[ library... ]
#include <thread.h>
size_t thr_min_stack(void);
DESCRIPTION
When a thread is created with a user-supplied stack, the user must reserve enough space to run this thread. In a dynamically linked execu-
tion environment, it is very hard to know what the minimum stack requirments are for a thread. The function thr_min_stack() returns the
amount of space needed to execute a null thread. This is a thread that was created to execute a null procedure. A thread that does some-
thing useful should have a stack size that is thr_min_stack() + <some increment>.
Most users should not be creating threads with user-supplied stacks. This functionality was provided to support applications that wanted
complete control over their execution environment.
Typically, users should let the threads library manage stack allocation. The threads library provides default stacks which should meet the
requirements of any created thread.
thr_min_stack() will return the unsigned int THR_MIN_STACK, which is the minimum-allowable size for a thread's stack.
In this implementation the default size for a user-thread's stack is one mega-byte. If the second argument to thr_create(3C) is NULL, then
the default stack size for the newly-created thread will be used. Otherwise, you may specify a stack-size that is at least THR_MIN_STACK,
yet less than the size of your machine's virtual memory.
It is recommended that the default stack size be used.
To determine the smallest-allowable size for a thread's stack, execute the following:
/* cc thisfile.c -lthread */
#define _REENTRANT
#include <thread.h>
#include <stdio.h>
main() {
printf("thr_min_stack() returns %u
",thr_min_stack());
}
