I'm developing a Python module in C that parses a very efficient protocol which uses dynamic integer sizes. Integers sent using this protocol can range in size from the equivalent of C's 'short' to a 'long long.' The protocol has a byte that specifies the type of variable being sent (from short to long long), but I'm not sure how to dea...
I am trying to setup allegro to work with visual stupid express 2008 but I can't find a set of instructions for the life of me. I just want to to recognize the allegro library.

I am using visual C++ Express Edition 2008. the tutorial is using the same thing. Is there away to get this or an alternative ?? This is my screen This is tutorial...
I got the error from error.c:31: /usr/include/ap/mas.h:254: error: expected specifier-qualifier-list before ‘time_t’ make: *** [error.o] Error 1 Feedback We at least need to see line 31 of error.c and line 254 of mas.h, with preferably a few lines of context around each. This error may have nothing to do with how time_t is being d...
How do I read input one string at a time to call another function in C. I thought this would work, but my output hangs: #define BUFFMT "%255" #define LINE_LEN 256 #define START_COUNT 1 // filename is declared in the main file elsewhere. I know the file opens since I tried an //old method I use to read one line at time using fgets, bu...
I'm trying to create a singly linked list from an input text file for an assignment. I'm trying to do it a little bit at a time so I know my code is not complete. I tried creating the head pointer and just printing out its value and I can't even get that to work, but I'm not sure why. I included the struct, my create list, and print l...

Years ago I had a little #define which I used in Borland C++ Builder. From memory, it was something approximately like #define BREAK_IF_DEBUGGING asm(0xA3); or something like that. It relied on 0XA3 (or whatever it was) being the op code for the interrupt which Borland were using to trigger a breakpoint. Can I do the same thing in...
I'm basically trying to create a linked list from a text file and add a new member every time the words are different, and increment the count if the words are the same (hw assignment). I thought I did it correctly, but it seems to add a member no matter what. I'm wondering if I'm traversing the list incorrectly while I search? Here i...
hi, I am porting our application from solaris sparc to solaris x86 and I encountered a size differences of struct between these two architecture. for example; I have a struct like typedef struct mystructS { double a; double b; double c; double d; double e; double f; double g; double h; double aa; double ab; doubl...
Hi, i am very new to unix/linux/c which i guess is why i am in this predicament. Anyway, i have just completed a c programme assignmnet and am trying to run it from linux terminal. So far i can create the main programme by navigating to the folder running gcc myFile.c then doing .a/.out this then runs my programme from the terminal wi...
I have a bash script in which i check the exit code of a last run command by using $? variable but now I am executing a C program (from that script) which returns 0 if the program gets executed successfully. Is there any way I can catch this return value of the C program from with in my bash script? I believe different commands like awk...
I have following code(part of code): snprintf( command, sizeof(command), "%s -o %s -n \"%s\" -st %s -et %s -a \"%s\"", _pcOPMTRExePath, _pcTempFile, l_acHostName, _pcStartTime, _pcEndTime, l_acMessage ); printf("%s",command); l_iRetValue = system(command); /* Return an error if failed to copy*/ if(l_i...
I have used unions earlier comfortably; today I was alarmed when I read this post and came to know that this code union ARGB { uint32_t colour; struct componentsTag { uint8_t b; uint8_t g; uint8_t r; uint8_t a; } components; } pixel; pixel.colour = 0xff040201; /* ---- somewhere down the...
If I place atexit( fn ); on the exit stack, it will get executed when the program exits: returns from main() or via exit(). Can I remove it from the stack? Why do I want to do this, you ask? I was experimenting with a simple try-catch mechanism using atexit, setjmp and longjmp. It would be just perfect if I could undo-atexit(fn); - ev...
may I know the meaning or even how to read this: srandom( time( NULL ) )? ...
Hi, I was wondering if someone could please help me with this: printf("Enter path for mount drive (/mnt/Projects) \n"); scanf("%s", &cMountDrivePath); Is it possible to allow the user to simply press Enter and accept the default (in this case: /mnt/Projects)? At present, if the user presses Enter, the cursor simply goes to the nex...
How am I able to access a static variable from another file? Doesn't static variable have a file scope? bash-3.2$ ls a.c b.c bash-3.2$ cat a.c #include <stdio.h> static int s = 100; int fn() { /* some code */ } bash-3.2$ cat b.c #include <stdio.h> #include "a.c" extern int s; int main() { printf("s = %d \n",s); return 0; } bash-3....
How come ceil() rounds up an even floating with no fractional parts? When I try to do this: double x = 2.22; x *= 100; //which becomes 222.00... printf("%lf", ceil(x)); //prints 223.00... (?) But when I change the value of 2.22 to 2.21 x *= 100; //which becomes 221.00... printf("%lf", ceil(x)); //prints 221.00... as expec...
Hi all, I am just wondering if there are any usefuls tools out there that allow me to exploit the Instruction-Level-Parallelism in some algorithms. More specifically, I have a subset of algorithms from the multimedia domain and I wonder what is the best way to exploit ILP in this algorithms. All this algorithms are implemented in C, so ...
