Right away I can see that your server is not reading the request from the client. So how does your server get the country value or does it send everything with each request?

Here's the return value of strmp RETURN VALUE The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2. The ! operator negates …

Try int getc(FILE *stream);

[QUOTE=ronnyrhymes;1293582]Thanks faxo and ancient dragon. Ancient Dragon i tried out your code however no value was printed out. Faxo, I also think its a good idea to use the fgets. However it should have been just gets since i'm not dealing with files over here.[/QUOTE] Not sure what you mean …

If you interested in 'low level' and kernel programming then may I recommend picking up a book on inline assembler. [url]http://ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html[/url] Plus I would investigate several books on kernel/operating system programming.

Try including the header file stdio.h

Could you post the program...

[QUOTE=Ancient Dragon;1280626]There is an old saying -- "garbage in, garbage out". What you posted is not even C code. I don't know what it is, but he certainly isn't C or C++ languages.[/QUOTE] That would be the output of the GNU gdb (debugger)....And yes C does blow sometimes. Maybe if …

When a function returns, it uses whatever is in the %rax register as its return value. Your function may inadvertently be placing the right value in %rax. Note: I won't rely on this behaviour.

[QUOTE=dsrepublic;1279641]AD, thanks for the help. I'm still having trouble understanding the first part though. Could you explain how (int *)(pc+i)== pa + 3 yields i = 12?[/QUOTE] I quickly looked at your posting and have one question int *pa=arr What's arr?

I'm no expert programming with 16 bit Intel or boot floppies(only did it once out of curiosity) but here's a website that addresses your question [url]http://www.emu8086.com/assembly_language_tutorial_assembler_reference/asm_tutorial_09.html[/url]

[QUOTE=csmgsarma;1276886]@ Ancient Dragon, if both are same,why is there a difference in code size in both cases. The initialization of global variables happens before the main() takes off, loosly at the startup. Isn't it?[/QUOTE] Please read Ancient Dragon's post for the answer.

Try strtol() long int strtol(const char *nptr, char **endptr, int base); DESCRIPTION The strtol() function converts the initial part of the string in nptr to a long integer value according to the given base, which must be between 2 and 36 inclusive, or be the special value 0.

Why don't you try it and find out...

Help you....With what?

This is what my help files say about fgets return value... char *fgets(char *s, int size, FILE *stream); gets() and fgets() return s on success, and NULL on error or when end of file occurs while no characters have been read.

You may want to investigate conio.h or curese.h libraries for this behaviour.

Woah...Don't use gets(). You run the risk of a buffer overflow, instead use fgets().

[QUOTE=baillot;1266003]Hello I am sorry if this is a dumb question but is it conceivable to determine the memory address of a function that is inside a running application from another application? Say I have an application A that has a function helloWorld(). A is being launched. I would like to …

Well if you need to map the file's contents into the user's address space, then use mmap().

Myself, I've always preferred a simple editor like Gedit or Vim.

bst.h Is a header file. You don't compile header files. If your looking for the process, creating a library, you should state for which operating system and compiler and type of library.

In C octal numbers start with a zero like 01234;

I have a question about functions and pointers to functions.... Why does a C program treat a function call to a function and a function call to a function pointer the same?

try this printf ("value : %u\n", *(unsigned char*)(p + i)); This will cast and dereference a byte starting at p + i...You had casting and dereferencing an int starting at p + i which will overflow past n = 0x000000ff.

[CODE] mystruct* A; [/CODE] You define A as a pointer to mystruct but never assign or allocate memory for it.

Here's a blurb from manpages malloc which discusses buffer overflows(its in the second half).
