I aim to integrate libmySQL into my executable instead of using libmySQL.dll. I use VC++ 2008 @ Windows Vista. I've downloaded "mysql-connector-c-noinstall-6.0.2-win32-vs2005.zip" from http://dev.mysql.com/downloads/connector/c/ It contains only ".h" files with declarations. Where is the implementation code (".c" files)? As said, I wi...
Hello. I am looking for ANSI C HAT-trie implementation released under some free license. I have not found one. Can you point me to some standalone implementation or a program that uses HAT-tries to get at least slight idea how to implement it the roght way, please? The original paper on HAT-trie can be found here: http://crpit.com/conf...
I would like to create a static (file scope) table of data pointer, data size and data version. The problem is that the data are in external files, but constants in the extern files. Example: file1.c const unsigned char data1[] = { 0x65, 0xF0, 0xA8, 0x5F, 0x5F, 0x5F, 0x5F, 0x31, 0x32, 0x2E, 0x31, 0xF1, 0x63, 0x4...
I have the following code: typedef __int64 BIG_INT; typedef double CUT_TYPE; #define CUT_IT(amount, percent) (amount * percent) void main() { CUT_TYPE cut_percent = 1; BIG_INT bintOriginal = 0x1FFFFFFFFFFFFFF; BIG_INT bintAfter = CUT_IT(bintOriginal, cut_percent); } bintAfter's value after the calculation is 14411518807...
I am wondering if it is possible to have werror in gcc/g++ exclude certain files (ones that I do not have source code to modify) so that I can continue using werror in a uninhibited state. ...
Suppose I write my code very defensively and always check the return types from all the functions that I call. So I go like: char* function() { char* mem = get_memory(100); // first allocation if (!mem) return NULL; struct binder* b = get_binder('regular binder'); // second allocation if (!b) { free(mem); ...
Is this illegal/dangerous? int* static_nonew() { static int n = 5; return &n; } The compiler doesn't seem to have a problem with it, but is the pointer location itself protected from being overwritten when someone else needs memory? EDIT: A little bit more of an explanation of why I asked this question. Note: I'm programming ...
I decided it would be a fun side project to do some work on tsocks, since it hasn't seen any updates in 8 years. It's hosted here on GitHub. I only made cosmetic changes to the code so far, but now I've run into a compiler error. According to dlopen(3): The obsolete symbols _init() and _fini() [...] Using these routines [...] is not r...
Hi, I am trying to calculate 100! I am looking for the simplest way to accomplish this using C. I have read around but have not found a concrete answer. If you must know, I program in Xcode in Mac os X. Thanks! ...
I have an old machine in my house and one of the things this machine does is detect whether a particular door in the house has just opened or closed. Right now, I have that machine post a tweet on a private Twitter account. I would now like to give this machine its own AIM account and have it send me a message on AIM. The only message...
how can i create a DLL of a program written in c program..?(am using turbo c compiler) the same program i could use with c# or VB program as- DLL reference.. http://support.microsoft.com/kb/106553 check out this link(i didn't understand this..) ...
So I'm far from an expert on C, but something's been bugging me about code I've been reading for a long time: can someone explain to me why C(++) programmers use typedefs to rename simple types? I understand why you would use them for structs, but what exactly is the reason for declarations I see like typedef unsigned char uch; typedef ...
What are some best practises for prototyping a filesystem? I've had an attempt in Python using fusepy, and now I'm curious: In the long run, should any respectable filesystem implementation be in C? Will not being in C hamper portability, or eventually cause performance issues? Are there other implementations like FUSE? Evidently c...
I'm working in a micro controller using C language. In this specific micro, the interrupts have to be defined using #pragma in following way: static void func(); #pragma INTERRUPT func <interrupt_address> <interrupt_category> static void func() { /* function body */ } The <interrupt_address> is address of the interrupt in vector table...
C99 still isn't supported by many compilers, and much of the focus is now on C++, and its upcoming standard C++1x. I'm curious as to what C will "get" in its next standard, when it will get it, and how it will keep C competitive. C and C++ are known to feed on one another's improvements, will C be feeding on the C++1x standard? What ca...
C++ is often touted as the evolution of C, which it is not. To draw an analogy for the kind of language I'm looking for: {Perl, Python, Ruby, Groovy} {C++, D} {Java, C#} {C, Fortran, Modula-2?, Pascal?, Go?} Do any proposed, or implemented languages fit in the same (enormous) niche as C, with the intention of being an alternative, wh...
Hi, I'm working on optimizing an application . I found that i need to optimize an inner loop for improved performance. rgiFilter is a 16 bit arrary. for (i = 0; i < iLen; i++) { iPredErr = (I32)*rgiResidue; rgiFilter = rgiFilterBuf; rgiPrevVal = rgiPrevValRdBuf + iRecent; rgiUpdate = rgiUpdateRdBuf + iRecent; iPre...
I have tried to read up on the subject but when I try to run what I thought would be the correct thing it doesn't do what I want it to :) I have a main program, that should take three mandatory arguments, let's call them t, p and s. Then I have several modules that, as a part of their initialization, also rely on command line arguments....
Hi All, I need to send the arp of a IP to get it's mac address which is configured on different machine. I am arping this ip from a C program by "system(arping -c 3 -i eth0 ) but I see that this is hanged in there. But if I run the same command from bash "arping -c 3 -i eth0 " it get executed successfully. I could not understand why ...
I am working on a defect in my GTK code for displaying context menus. After creating a menu with a number of menu items, I use gtk_menu_popup() to display the menu. This function takes a function pointer of type GtkMenuPositionFunc which lets me position the menu. I don't really do anything here except tell GTK to keep current position b...
