c++ - Any RAII template in boost or C++0x -

-

क्या RAII के लिए कोई टेम्पलेट उपलब्ध है? इसमें scoped_ptr , shared_ptr जैसी कक्षाएं हैं, जो मूल रूप से सूचक पर काम करती हैं। क्या उन वर्गों को पॉइंटर्स के अलावा अन्य किसी भी अन्य संसाधनों के लिए इस्तेमाल किया जा सकता है क्या कोई टेम्पलेट है जो सामान्य संसाधनों के साथ काम करता है।

उदाहरण के लिए कुछ संसाधन जो एक दायरे की शुरुआत में हासिल किया गया है और किसी भी तरह से गुंजाइश के अंत में जारी किया जाना चाहिए। अधिग्रहण और रिहाई दोनों कुछ कदम उठाते हैं। हम एक टेम्पलेट लिख सकते हैं जो दो काम करता है (या शायद एक ऑब्जेक्ट) जो कि यह कार्य करते हैं मैंने इसे सोचा कि यह कैसे प्राप्त किया जा सकता है, मैं सोच रहा था कि ऐसा करने के लिए कोई भी मौजूदा तरीके हैं

संपादित करें: कैसे के बारे में एक के लिए सी ++ 0x समर्थन के साथ लैम्ब्डा फ़ंक्शन

shared_ptr निर्दिष्ट करने की संभावना प्रदान करता है जब पॉइंटर को नष्ट करने की आवश्यकता होती है, तो डेलीटर को लागू किया जाएगा और जो भी सफाई कार्य आवश्यक हैं वह कर सकते हैं। इस तरह से सरल पॉइंटर्स की तुलना में अधिक जटिल संसाधनों को इस स्मार्ट पॉइंटर वर्ग के साथ प्रबंधित किया जा सकता है।

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.

tsql - Correct sql/hql query (aggregate in where clause) -

-
I want to query the query as below but the question is wrong but describes my intentions. select name, date time, data from record, date time = maximum (date time) Update: OK The description of the query intentions is not very good. My bad I want to select the latest record for each person. i like Mickey's answer and quosnoye (and upyoyed miki), but if your needs are similar to me , You should keep in mind some limitations. First and foremost, this works only when you are looking for the latest record or latest record for the same name. If you want the latest record for each person in a set (a record for each person but the latest record for each), then the above solutions are small. Second, and less importantly, if you work with a large dataset, then it can be slow for a long time. So, what's around the work? Whatever I do is to add a small field to mark the "latest" in the table. Then, when I store a record (which is done in the stored procedu...
