How to use Compare and Swap (CAS) atomic function(Solaris specific) in C

Hi,
I have found cas32() atomic function in (solaris 10) </usr/include/sys/atomic.h> (and also there is another atomic.h header file in </usr/include/atomic.h> but this header file does not have any cas32() function declarations) the declaration of cas32 in <sys/atomic.h>
is as follows
extern uint32_t cas32(uint32_t *target, uint32_t cmp, uint32_t newval);
extern ulong_t caslong(ulong_t *target, ulong_t cmp, ulong_t newval);
extern uint64_t cas64(uint64_t *target, uint64_t cmp, uint64_t newval);
extern void casptr(void target, void cmp, void newval);
extern uint8_t cas8(uint8_t *target, uint8_t cmp, uint8_t newval);
But the problem is when iam using these functions in c programs and compiling
using gcc it is showing the following error.
Undefined first referenced
symbol in file
cas32 /var/tmp//ccQcsnev.o
And if i use the function other than cas32 group of instruction
such as atomic_or_uint()
whose declaration is extern void atomic_or_uint(uint_t *target, uint_t bits);
in <sys/atomic.h> it is giving no error where as for CAS32 it showing as undefined symbol.Why it is giving like that we are not able to know.Is it the case that CAS32 instruction only available in Kernel mode and not available to user mode.Please inform us if anyone knows how to use cas32() instruction in the user C programs.As this is usefull for writing Nonblocking versions of stacks and Queues.Is there any way to write
our own atomic functions?

You are trying to use the old kernel-only CAS functions, use the correct ones like:
atomic_cas_32.

I would like to know how can i compare a switch case 1 and case 2 in C# is it possible to do that? obs i am a begginer :)

i would like to know how can i compare a switch case 1 and case 2 in C# is it possible to do that? obs i am a begginer :) I tried to do it with search and sort but it did not go well

let me give you an example if you add a word case 1( lagg ord) how can i compare that word with case 2 words ( in case 2 already exist 5 words)
here is the my program
using System;
namespace ConsoleApplication1
class Program
static void Main(string[] args)

bool utgång = false;
do
int Valet;

try
Valet = int.Parse(Console.ReadLine());
catch (Exception)
Console.WriteLine("Du skriver fel character!\n" +
"\nSkriv bara mellan 1 och 4");
continue;
switch (Valet)
case 1:
Console.WriteLine("\n lägg ett till ord! ");
var input = Console.ReadLine();

MultiThreaded compare and swap question.

I'v got this assignment and I'm not sure which approach to take. I think I've got it right with my second try, but I was wondering if I could get some sort of verification or something.
"Use Java monitors to implement the atomic Compare-And-Swap instruction, which has the following effect: CSW(a,b,c): < if (a==c) { c = b; return(0);} else {a = c; return 1;} > (In most concurrency books and papers instructions within angle brackets < > means that everything within the brackets is done in one uninterruptible, atomic action.) "
Is this right?
public synchronized int compareAndSwap(Object a, Object b, Object c)
        if ( a.equals( c ) )
            c = b;
            return 0;
        a = c;
        return 1;
    }Or is this?
public int compareAndSwap(Object a, Object b, Object c)
        synchronized ( a )
            synchronized ( b )
                synchronized ( c )
                    if ( a.equals( c ) )
                        c = b;
                        return 0;
                    a = c;
                    return 1;
    }Or am I totally off base? I think the latter is right as it prevents the objects themselves from being messed with.

As far as making it an atomic action, you do that
with synchronized, BUT more detail might be needed
about the context in which it's supposed to be atomic
to know what to sync on.OK, thanks. I was thinking I was crazy or something, but his question is just unclear. I have no idea what he wants and I'm not sure he does either.
Thanks.

Problems analizing compares and swaps in my algorithims

What I need to do is analize my sorting algorthims, in terms of the number of compares and swaps. I have about 6 different sorts in one class, a couple of them came from help by, other posters, on this board. And I have a simple file reader in another class that reads a txt file, sorts, then prints, but also prints the numbers of compares, swaps, using varibles from my sorting class.
The txt file has 64 strings(names of people). Some of the sort I get what seems to me correct, or least close to correct results, but for a couple I"m getting downright strange results. I'm trying to figure out where to put the counting variables so I can get decent results.
In my quicksort, the results I'm getting is 1 compares 1 swaps, now obviously that's wrong but I'm trying to figure out where to put, the variables to get the correct results.
     public static void quicksort(List data, int first, int last){
                       int lower = first + 1, upper = last;
                       swap(data,first,(first+last)/2);
                       Comparable Bound = (Comparable)data.get(first);
                       while (lower <= upper){
                            while ((((Comparable)data.get(lower)).compareTo(Bound)) < 0)
                                      lower++;
                            while (Bound.compareTo(data.get(upper)) < 0)
                                 upper--;
                            if (lower < upper)
                                 swap(data,lower++,upper--);
                            else lower++;
                       swap(data,upper,first);

                       if (upper+1 < last)
                            quicksort(data,upper+1,last);
      public static void quicksort(List data){
                       if (data.size() < 2)

                       for (int i = 1; i < data.size(); i ++)
                            if (((((Comparable)
                       data.get(max)).compareTo(data.get(i))) < 0))
                                 max = i;
                       compares++;       // <----------------------- COMPARE
                       swap(data,data.size()-1,max);

How to use IDOC and RFC adapter in 1 scenario?

We have AAA field and BBB field and we want to send AAA field to receiver sap system using IDOC adapter and BBB field to receiver sap system using RFC adapter. But how to use IDOC and RFC adapter in 1 scenario and how to map and what are the design and configuration objects we require to create?

To achieve this you have to use
Two Interface Determinations
Two Communication Channels (IDOC & RFC)
& Two Receiver Aggrements.
Use the Enhanced Interface determination and give your conditions there. Based on you condition your interface mapping will be triggered and data will be sent to IDOC & RFC respectively.

HOW TO USE LOGICAL AND OR CONDITION TOGETHER

hi,
You cannot use the logical and or condition together at the same time in SQL statement. Sachin is correct while using the and and or in the same condition. You can get the data using or condition in SQL statement, and then use the delete statement of internal table using the end condition. please find the following code for the same.
select *
from dtab
where cond1 eq 'A1'
or cond2 eq 'A2'.
if sy-subrc eq 0.
delete itab where cond1 eq 'A1' and 'A2'.
endif.

Query: how to use structure and selection and what's the difference between

Query: how to use structure and selection and what's the difference between these two?
Would be appreciated if some experts here give examples to demenstrate on how to use structure and selection in query and what's the difference between these two?
Thanks in advance!

Hi Kevin,
1. Well by default all the KF that you include in your query go into a Key Figure Structure. You can additionally have another structure for defining how your chars are laid out. A common example is a Calmonth structure where you have selections for 12 months, quarers and YTD values. This would be a char structure with different selections (for each month, qtr etc)
2. Yes, a selection with a KF is the same as restricting a KF. You can use am RKF is you have one on the left hand side, or if you need to do this locally in the query, right click the structure and choose New Selection, then proceed to choose your KF and reqd char values.
Hope this helps...

Workflow Components : how to use SPLIT and JOIN ?

Dear all,
Because a Transition does not have any return of result, do you know how to use SPLIT and JOIN components ?
<activity name='"xyz">
<Transition to='act1'>
</Transition>
<Transition to='act2'>
</Transition>
</activity>
In this above example, the second transition towards act2 is never called (i.e. there is no condition for the first transition) because there is no return of result for the first transition.
Unfortunately, I didn't find any documentation about the SPLIT and JOIN workflow components. Do you have some information about these components ? How to use them ?
Thanks a lot.

<activity name='"xyz" andSplit='true'>
<Transition to='act1'>
</Transition>
<Transition to='act2'>
</Transition>
</activity>
The "andSplit='true'" will cause it transition to both act1 and act1.
