Trouble loading DLL
Brent, Each executable is limited to a specific default size by the OS. When you dlopen() a library your executable's memory requirements increase by the size of the library. I think your program is running out of memory. This max size per executable can be increased by the executable. In... -
scanning directory
getdents() offers a relative fast solution. otherwise you can try something like fopen("my_filename","r") if it succeeds my_filename is present,otherwise it is not. To make the code even faster you can use the stat() system call. cheers amit crazy_indian@lycos.com to... -
How can i run a timer in the background and let the rest of the ....
If you are using a UNIX clone you cna use signal handling to create a timer. One way is to use the alarm() call. The alarm() system call instructs the alarm clock of the calling process to send the signal SIGALRM to the calling process after the number of real time seconds specified by sec... -

Limited sorting.
Cool find Ed,I kept searching for the same solution but I wasn't able to find out how to print the line number, I tried the ed command but I coudn't make it work. A star for you. How about pr -n -t data.file|sort -k 3 | sed s/^[0-9]* /""/g (Not tested) We can remove the -k 1 for some...- ami123

Limited sorting.
I dont think you are missing any trick,you have to go the hard way. You have to write your own sorting finction which uses the second parameter i.e. A,A,B,B,D etc as primary keys and the linenumber of each of them as the secondary key. amit crazy_indian@lycos.com to bug is human to debug...- ami123

where does main() function in C program return in linux ?
Anjanku, I would say that you should be a little bit carefull about the return values of sytem calls in Linux. Linux is currently not compliant with the standards and its errno policy is quite different from traditional UNIXes. The best way is to read the man pages. And yeah echo $? will give... -
C ---- external variables
dchoulette's description is accurate. If you want to see some more examples open the /usr/include/stdio.h file. And check out the definitions of file operations.printfs etc. e.g.(from stdio.h) extern FILE *fopen(const char *, const char *); extern FILE *freopen(const char *, const char... -

Check if your library has the itoa() function. If it doesnt you will have to write your own version or download it from the web. cheers amit crazy_indian@lycos.com to bug is human to debug devine -
Character validation on mainframe
This should be an easy task. The code would look something like this... main() { char *buffer[LINE_MAX]; FILE *fp_r,*fp_w; fp_r=fopen("filename","r"); fp_w=fopen("destination","w"); while ( fgets(fp_r,LINE_MAX,buffer) != NULL) { if(... -
pointer's size
There is a hack that you can probably use. This is very hardware and compiler specific so the code wont be portable. And it will work only if the pointer has not been moved around. Hack malloc() normally stores the size of the allocation one word before the start of the array. i.e if malloc()... -
Object Files
Delorie is technically not a compiler. It is a development system/environment which uses the underlying gcc compiler to compile your source code. You can safely assume that cc and gcc are the same thing. cc is the traditional C compiler on UNIX machines. The GNU C compiler(which you are using)... -
i'm getting a segmentation fault wh
You have to really debug your code and see what the varaiable 'array' is assigned at the time of doing the malloc(), and check the value at the time of free(). If they are the same then you are most probably doing a double-free. If they are different then your variable has been corrupted by the... -
Object Files
Jolesen pointed out a good fact,the speed of the build.As he said you dont have to rebuild the files that haven't been modified. In addition many compilers allow different files to be build in parallel,i.e it will create different processes to build different object files and when they are all...
