hi, if it's not the wrong location of the fs.h file (i really doubt it is) ... then try this ... since the compiler is saying "dereferencing pointer to incomplete type" ... maybe it is that the struct u r passing to the function is not properly initialized ... like if the struct object u r passing to the function has been just intialized as struct buffer_head *structobbject; then structobject is not initialized ... try structobject = new buffer_head[1]; then u can pass structobject to ur function and use map->b_data within the function... this may work .. try it ... if this doesn't .. post again .. i'll think of something else. dinesh. - Perfection or Nothing.

[ILUG-BOM] RE: [ilugd] Enterprise Software Stack across operating Systems (fwd)
by Shuvam Misra 01 Oct '03

Dear all, We've just witnessed a debate about allowing /banning HTML mail. I received (or didn't receive, choose whatever you want) such a mail from ILUG Delhi, which highlights the problem of banning such mail. One member, Tarun Upadhyay, has done some hard work to create a table listing software available commercially and in open source, and has tried to start a discussion. His table, when sent in HTML, got blocked because ILUG Delhi blocks all attachments. When he sent it as in-line plain text, you can see what came through. I can't read head or tail of it because of the line wrapping, and I don't have time to manually re-format it just to read it. Tarun is probably going to try putting it up on some Website. Not all of us list members have access to such Websites, and the ILUG groups don't seem to provide this sort of Vault as a service to its members. (ILUG Delhi certainly doesn't seem to.) And if I were in his place, I wouldn't have taken the trouble to find a Website in this case; this table covers a subject fundamental enough for me to want to send it to all list members by email. I asked Tarun, by direct email, to send me the table as an HTML attachment. He did. My purpose was served. Is this a scalable model? If a hundred members of ILUGD (they have many hundred) had asked individually, should I expect that he'll oblige all of them? Who loses and who wins in this case? I'd say the whole mailing list loses, because no discussion really happens, and Tarun Upadhyay's work "goes waste" in a sense. As it is, we know how rare it is for any member of any list to create any original content and submit it to the list. What would you suggest we should do in situations like this? My suggestion: all emails submitted with attachments should be forwarded with moderator approval (if Mailman permits such a filtering); It should not blindly be stripped of attachments. Just a thought. :) regards, Shuvam On Tue, 30 Sep 2003, Tarun Upadhyay wrote: > All right. All right. I figured out the hard way that I cannot send > attachments to the list.

List Guidelines
by Linuxers Admin 01 Oct '03

01 Oct '03

Welcome to the GNU/Linux User Group of Bombay (ilug-bom)! READ THESE GUIDELINES CAREFULLY AND FOLLOW THEM CLOSELY Now that you are a member you can read and post mails to the group. The messages have to be related to propogating, using, trouble-shooting, bug-fixing, of GNU/Linux operating system. Feature comparision of other operating systems and distributions is allowed, but restrain from BASHING. GNU/Linux is possibly the most friendly operating system, and hence as users of the OS let us all maintain a FRIENDLY tone to our conversations on the list. YOU are the best judge to determine the relevance or irrelevance of your post to GNU/Linux, and therefore you are responsible for your postings. Since this is not a moderated list, please read the guidelines before posting mails to the list. The sole functioning of this list is based on the self disciplinary nature of its users. ILUG-Bom Mailing List participation Guidelines 1. Keep paragraphs and messages short and to the point. See that what you are writing is useful to the mailing list. If not, send it as a private message to the person. (Note that by default the mails go to the LIST) Please change the sender address appropriately before sending a personal mail. 2. When quoting another person, edit out whatever isn't directly applicable to your reply. Don't let your mailing software automatically quote the entire body of messages you are replying to when it's not necessary. Take the time to edit any quotations down to the minimum necessary to provide context for your reply. Nobody likes reading a long message in quotes for the third or fourth time, only to be followed by a one line response: "Yeah, me too". Messages larger than 7k will not be posted immediately. Such messages will need the list admin's approval. 3. Focus on one subject per message and always include a pertinent subject title for the message, that way the user can locate the message quickly. Also please include a suitable header in case of Commercial / Offtopic mails. Do NOT use subject headers like "HELP", "One question". Most experienced users will simply ignore these mails. 4. Capitalise words only to highlight an important point or to distinguish a title or heading. Capitalizing whole words that are not titles is generally termed as SHOUTING! *Asterisks* surrounding a word can be used to make a stronger point. Use the underscore symbol before and after the title of a book, i.e. _Linux Configuration And Installation_ Underscores may also be used to signify _underlining_, while surrounding your text with slashes makes it /italics/. 5. Limit line length to approximately 65-70 characters and avoid control characters. This helps ensure that lines don't grow too long after several levels of replies. Remember that each reply adds one level of > to the start of the line. 6. NEVER send chain letters to the mailing list. A mail simultaneously sent to more than 10 users will not reach the list. This is to eliminate possible spammers/bulk mailers to reach the list. 7. Be careful when using sarcasm and humour. Without face to face communications your joke may be viewed as criticism. When being humourous, use emoticons (smileys) to express humour. (tilt your head to the left to see the emoticon smile) :-) = happy face for humour. 8. If a mail has offended you personally, please send a private message to the person expressing how you feel, instead of sending it to the mailing list. 9. Please remember that we have both male and female members. No gender abuse is allowed on the list, and do not include any gender specific slang in your posts. 10. Acronyms can be used to abbreviate when possible, however messages that are filled with acronyms can be confusing and annoying to the reader. Examples: IMHO = in my humble/honest opinion FYI = for your information BTW = by the way Flame = antagonistic criticism. http://www.jargon.org for more such acronymns. 11. Please provide URL's to articles wherever possible. Avoid cutting and pasting whole articles especially considering the fact that all may not be interested. In any case your posting may not be more than 7k. Occassionally if you may have to send such a mail, post it, it will reach the members after the list admin approves it. 12. When using the mailing list for commercial purpose, please prefix the subject line with "COMMERCIAL". 13. Please *read all your mails before replying* to a mail. Someone may have already answered it. 14. Remember that most of the people are paying by the minute for their internet access. Some pay per byte. Hence please do not waste bandwidth. Ensure your posts are in plain text only. Do not post html mails, or include attachments. Restrict signatures to not more than 4 lines of 72 column text. Do NOT include company disclaimers in your messages. 15. Any violation to the above will be given a warning. 5 such warnings and the subscriber will be suspended from the mailing list for 15 days.
