You've been around long enough not to post homework questions, so I'll answer: use setjmp() and longjmp(). Basically, the first call saves the current stack configuration (stack pointer, parent caller address, etc). The second call restores that stack configuration. So you might have some code like this:
I'm using the UNIX csh and i wish to use recursion to nav my way up (or down as it is) a given folder.
My little test script is called "r" and takes a folder as argv (or $1)
#!/bin/tcsh -f
set allFiles = `ls -A $argv`
cd $argv
while ($#allFiles)

I am running a korn shell script which has a recursive function.
The script ran for 117 iterations and ended up with the following error
"recursion too deep".
what should be done to avert this?
Thanks in advance

Hello every body. I am trying to find the factorial using the following code. But it is giving the syntax error. I tried very much but in vain. Thanks in advance for helping me

Hi Guys,,
I tried to create a recursive function in unix.
The following is the code.
#/bin/sh
function(){
n=$1;
if ; then
out=1;
echo "inside if for 0";
else
out = `$n * function "$n-1"`;
echo "inside if for $n-1;

Hi,
Question: how come the output is like that? Can explain to me abit. I am learning C.
Thanks!
#include <stdio.h>
#include <string.h>
void printit(char line_of_char, int index);
int main()
{
char line_of_char;
int index = -1;
strcpy(line_of_char, "This is a string.");

Can someone please explain me why the following script calls it self recursively:
#!/bin/bash
echo Called
$0
while this not:
#!/bin/bash
echo Called
$($0)

In the following command:
find / -ctime +3 -exec rm -R {}\;
how is the recursion list built for the actual rm ?

Not sure how to ask this question. I want concatenate strings and variable recursively into new variable. For example:
infile01=/dir/subfolder/file01.txt
infile02=/dir/subfolder/file02.txt
infile03=/dir/subfolder/file03.txt
for i in {01..03}

Hi,
I am trying to disable the recursion on DNS server (Solaris 10). I have added the lines in the named.conf as below:
allow-query-cache { none; };
recursion no;
Then restarted the solaris DNS services

Still I am able to... (0 Replies)
Hi,
I cannot find a way to copy a directory to another location with all attributes (mode, ownership, timestamps) but withOUT recursion (after so many years of working with Linux).
Say I want to create /home/jail/tmp exactly like /tmp but with nothing in it. Here is what I tried:

tcl_setrecursionlimit
Tcl_SetRecursionLimit(3) Tcl Library Procedures Tcl_SetRecursionLimit(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_SetRecursionLimit - set maximum allowable nesting depth in interpreter
SYNOPSIS
#include <tcl.h>
int
Tcl_SetRecursionLimit(interp, depth)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter whose recursion limit is to be set. Must be greater than zero.
int depth (in) New limit for nested calls to Tcl_Eval for interp.
_________________________________________________________________DESCRIPTION
At any given time Tcl enforces a limit on the number of recursive calls that may be active for Tcl_Eval and related procedures such as
Tcl_GlobalEval. Any call to Tcl_Eval that exceeds this depth is aborted with an error. By default the recursion limit is 1000.
Tcl_SetRecursionLimit may be used to change the maximum allowable nesting depth for an interpreter. The depth argument specifies a new
limit for interp, and Tcl_SetRecursionLimit returns the old limit. To read out the old limit without modifying it, invoke Tcl_SetRecur-
sionLimit with depth equal to 0.
The Tcl_SetRecursionLimit only sets the size of the Tcl call stack: it cannot by itself prevent stack overflows on the C stack being used
by the application. If your machine has a limit on the size of the C stack, you may get stack overflows before reaching the limit set by
Tcl_SetRecursionLimit. If this happens, see if there is a mechanism in your system for increasing the maximum size of the C stack.
