Allocators and what they allocate
Hallo Group, recently I needed to put a std::map into a shared memory segment and stumbled over an unexpected problem (never having implemented an allocator before): What is the "official" way to determine the size of a "node"? (I hope it is not: go create a dummy map with a dummy allocator, one that throws the actually allocated size when allocate() is called the first time... The value is needed to determine the size of the shared memory segment for N elements when needs to be completely pre-allocated.) (Although this dummy allocator method does seem to work ;-) Perha...

IPFW
Here's the situation. I run a low traffic family history/genealogy website on my local box. My "customers" are family members who access the site from their home machines, all of which - so far as I can tell - use dynamic ip addresses. My current firewall policy is "accept all", with daily additions to my bad guys (block) list. It's becoming tiresome, however, and I'd like to change policy to "deny all" while still allowing my present "customers" and any future additions relative ease of access. I'm fairly comfortable with IPFW confi...

Changing iptable policy
All, I am trying to use set up a syslog server to capture syslog events outside a firewall. So, I am using Redhat 9.0 (Linux version 2.4.20-8) and IPTABLES to prevent unwanted access. The issue I am having is changing the policy. I want to create a new chain and have the policy to changed to DROP. Each time I enter the command iptables -P FIRE DROP, I get the following error message: iptables: Bad built-in chain name However, if I change one of the default chains of INPUT, FORWARD or OUTPUT with the command iptables -P INPUT DROP, the command is accepted. What am I missing? tjcreek55@y...

changing password policy
hi and happy new year to all of you out there i am a new user of linux (RH9.0) I am facing two problems: First one is that i am unsure how do i change the password policy of my system i mean that whenever any user want to change his or her password then the new password should be of how many characters and which all type of characters must be used in that new password. kindly be eleborate if possible. Second problem is that when i give shutdown command my system goes down but gives me a message of "power down" or "system halted" and then i have to manually switch the system...

ALLOCATE and contiguous memory
Are ALLOCATABLE arrays stored in contiguous memory, as regular arrays are? There is a post in another thread which involves an array that seems to be passed to a C program that expects an array contiguously stored in memory. The user is calling it with an ALLOCATABLE array, but then the documentation doesn't say not to do that. -- glen "glen herrmannsfeldt" <gah@ugcs.caltech.edu> wrote in message news:AmMad.351665$mD.221142@attbi_s02... > Are ALLOCATABLE arrays stored in contiguous memory, as > regular arrays are? > "A non-pointer array occupies a seque...

Is string allocation contiguous?
We know that vector<T> is required to be contiguous, that is, &vec[i] == &vec[0] + i if i < vec.size() But what about basic_string? Originally, it was specified that str[i] == str.data()[i] if i < str.size() This of course can't happen in the non-const case, but I assume that implementations use a non-const "_internal_data()". Anyway, the above statement implies &str[i] == &str[0] + i, which is the same as for vectors. The current working paper modifies this paragraph (21.3.4) as: str[i] == *(str.begin()+i) if i &...

Contiguous memory allocation
Hello, I try to allocate a memory block of 256MB using 'AllocateCommonBuffer', but I am able to allocate a maximum of 128MB of memory only. The system has 8GB of RAM ! I tried running the de-fragmenting software to use if that could be the issue. Any idea ? Thanks, Srivi. So what? Such large common buffers are not supported, at least on 32bit OS. The OS just could not find the _contiguous_ memory area of this size, that is normal. Try redesigning your solution to not require such huge common buffers. -- Maxim Shatskih, Windows DDK MVP StorageC...

allocate contiguous memory
Hi, I have a wdm kernel driver which needs a contiguous memory space of 2 MB. The memory is allocated with the AllocateCommonBuffer routine which is available if you use a dma adapter. So far so good. This is working on my test pc (intel dual core with 1 GB internal memory). However, at the pc from the customer it fails during installation of the driver (when the driver is started, the memory is allocated). If I tell the system to restart before using the driver (by using the reboot keyword in the .inf file), everything is fine (no problem with allocating the memory). What cou...

allocating contiguous memory
How can I allocate contiguous memory in a WDM driver. The call MmAllocateContiguousMemory needs the ntddk.h headerfile, and this file cannot be included when the wdm.h headfile is included. So my conclusion is that WDM drivers may not use this routine, but what is the alternative?

Trace on change/Signal on change/Call on change
Is ooRexx getting any closer to having a mechanism which could be used to trace when a particular variable or stem variable gets changed (to a particular value)? I don't know whether I'm writing cleverer bugs, or my debugging skills are waning with age, but it is starting to take me days to track down some problems that would be a snip with a variable monitor. I've just fixed such a bug. It took me about three years, because it happened only once a year, on average.

confusion about algorithm of allocating space, allocate() in alloc.c
hi, I am new here, and I just started to learn lcc with the text "A retargetable C compiler". I am so confused with the algorithm of allocating space stated in Chapter 2 of the text.

iTunes changed my changes
Don't know when it happened- could have been with the update of iTunes prior to the update of iOS7, but here's what happened: A few weeks ago, I changed the name of the four movements of a Mozart Symphony so that it would appear separately from the exact same symphony by another artist. This is the default which I had: Mozart: Symphony #41 In C, K 551, "Jupiter" - 1. Allegro Vivace which I changed to: Mozart: S41 In C, K 551, "Jupiter" - 1. Allegro Vivace The separation worked as expected. BUT: Somewhere, somehow the changes got reverted to what ...

Sun changes patch policy
As announced on SunSolve, there will be further changes to Sun's patch access policy. Access to the anonymous FTP server to download patches will cease from August 2006. Additionally, any access to Sun patches without a Service Plan will require a "Sun Online Account" and the acceptance of the Software License Agreement from mid July 2006.

Changes and frequency of changes
Hi, I observe variable x over time (from 1999-2005) for a large number of firms, w. I have computed the change in variable x from one year to the next. Now, I would like to identify whether variable x has changed from one year to the next for each firm as well as how often it changed for each firm(in some cases I expect no change in this variable i.e. 0). Any suggestions on how to do this in sas?

Apple change their notification policy?
Okay, I ordered a 24" iMac and the new airport router. I got to wondering why I got no notification of them, not even a confirmation email on the order. I *know* they have my address, but it has worked in the past for other orders, and I get the little marketing blurb stuff from them periodically. (Yes, I could turn it off probably). Well anyway, luckily I had printed the order page when I submitted it, so I went and the order status lookup on the web and sure enough not only is the order in the system, but the iMac itself has already shipped, the base station is supposed to ...

Net result; one customer lost for ever, one Reward Card returned. By the way, is there anywhere now in UK who still accepts returns? Regards Pa...
