#define true 1 #define false 0 typedef int bool; This is a bad thing to recommend given that there is a standard header stdbool.h for the same purpose. And since it is C99, it should be there on any system. It was just a simple code snippet to indicate bool can be quickly added. I agree, it should not be used exactly as mentioned since the naming is too generic. OP can chose whether to use stdbool.h or add 3 lines to his code, to me this is just a moot point. -- 0 ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Ie, true is the opposite of false. This is the only way to ensure that a test against 2 true values will work in all cases. If you meant to say #define true !0 that is not going to work. Checking true against a variable with non-zero value will still fail. [ if(a == true) is same as if(a == !0) which will fail] C99 booleans automatically converts all values to one or zero according to standard rules before storing it in the variable. Therefore they should be used in preference to defining our own and using integers as kludge. -- அகிலன் (Akilan R) [ blog.akilan.in ] *I should have no use for a paradise in which I should be deprived of the right to prefer hell.* --Jean Rostand ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

No, C99 and stdbool.h are much more than that. It simply defines bool to be _Bool which is not same as integer typedef you define. _Bool is a full fledged boolean variable that can convert other values to 1 or 0 when stored according to standard rules in a transparent way. In fact one need not use stdbool.h if one is happy with typing _Bool.

No. It is very important to stick to the standard. In C's rationale, existing code is extremely important while existing implementations are not. [1]. Therefore, #defines like this still work and probably will work for eternity. But standards are established for a reason. They define the interface or guarantees that are offered by the language. A language MyBreakyC may choose to define 1 to be true and 0 false in one implementation and the other way around in another. The programmer is expected to use names like true and false to stay safe. --- Ashok Gautham [1] www.open-std.org/jtc1/sc22/wg14/www/C99RationaleV5.10.pdf Page 9, Line 20 ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

I was under the impression that it was all done in the headers but apparently not. Its nice to know there is a boolelan datatype. Although, it is wierd they chose _Bool instead of bool. I guess, that would break code which had already defined a bool macro. Talk about legacy stuff... -- 0 ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

If using a document management system or content management system fits in to your plans, you may consider KnowledgeTree, which has configurable workflows. If you are already on Drupal, you may look at the module workflow, which lets you control various stages before an article is published. Since you are going to use the system for holding the articles for publication into a pdf document ultimately, in either of the above systems, defining a workflow state approved for publishing as the final state, instead of published, should serve the purpose.

[Ilugc] What should be the problem?
Dear luggies, One of my friend is running his laptop powered with LinuxMint 11 + dual boot windows and he uses Reliance Broadband + USB Modem manufactured my ZTE corporation for internet connection. According to his Data plan when some data limit is reached, the speed of connection will drop from 3.1 Mbps to 256 kbps. When the speed drops, he is unable to get internet connection in linux and he can access internet via windows in the same laptop using the Front-end developed for the modem. Now whats happening? What should be the problem? How can this be resolved? He feels like just for this reason i need to switch to windows (he wants a solution for this in linux). Even i have tried in my laptop running fedora 16 updated till date and modem gets detected, configuration done, yet not getting connected. Thanks in advance :-) -- Regards, Prasanna Venkadesh PuduvaiLUG (puduvai Linux Users Group): http://puduvailug.wordpress.com/ FOSS Jobs all over India: http://fossjobs.in ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

What should be the problem? How can this be resolved? I am not sure if this is the case in your scenario, but seems logical to put this forward: The speed drop is not bandwidth control. It is actually because the connection itself switches to a different technology (Broadband+ and High speed 1x in my case). To switch the modem to connect using the lower speed technology might be a proprietory AT command. Since the Windows front end can do this for you, it is able to connect in low speed.
