Yes, it seems gedit does not count the bytes correctly (and me neither). strlen states 6 bytes.

I get this Valgrind error while using malloc but if I use calloc then there is no error.

I allocate 8 bytes for the string inside sprintf, 12 for the ip and 1 for the string terminator. This...

Debian lenny uses the 2.6.26 kernel by default. Can I compile the most recent kernel from kernel.org and use it instead ? Will the new kernel be incompatible with other installed softwares ?

-c will not work. I have an old sudo version ?

user1@debian:~$ sudo -u user2 -H -c "ulimit -S -c unlimited"
sudo: illegal option `-c'
usage: sudo -h | -K | -k | -L | -l | -V | -v

When I use sudo with ulimit there is an error but if I use ulimit without sudo there is no error.

In bash:

user1@debian:~$ sudo -u user2 -H ulimit -S -c unlimited
sudo: ulimit: command not...

I am trying to follow this article: http://www.w00w00.org/files/articles/heaptut.txt

This article's example successfully uses memset to overwrite a pointer's address while making it overflow to...

1. Why are the pointers' addresses every 32 ?
2. Am I correct in stating that memset is writing to memory that is not allocated to any of the 3 pointers ? Is it writing to memory in between the...

I have successfully linked ld-2.7.so by compiling like this:

gcc -std=c99 -D_POSIX_C_SOURCE=200112L -O2 -m32 -s -Wl,-dynamic-linker,ld-2.7.so myprogram.c

But I have not managed...

The gcc version is different on my computer than on the remote computer. An ldd on my program says:


Is there any way I can tell gcc to compile my program against my version of libc-2.7.so and...

Ah, that's why. I thought it would only apply to the program being compiled.

By default, yes, because in ASCII, 1 char = 1 byte, but making it equal to 32 bits (4 bytes) would be better suited for...

My OS (Debian) and gcc use the UTF-8 locale. This code says that the char size is 1 byte but the size of 'a' is really 4 bytes.
int main(void)
{
setlocale(LC_ALL, "en_US.UTF-8");

Also, I would like to know if fopen, fread & fwrite are thread-safe ? Can multiple users fopen, fread & fwrite files at exactly the same time with no problems or is that the whole point why fcntl.h...

Yes, thank you, it is good to know that you can get file attributes even if the file is locked. I was not aware of access().

If a process already has the entire file locked for read and write using newstruct.l_type = F_WRLCK; what would happen if another process would try to open it in read only mode using open(filename,...

Thank you. Suggestions worked.

Why does this socket function only read the first 1440 chars of the stream. Why not the whole stream ? I checked it with gdm and valgrind and everything seems correct...



#include <stdio.h>...

1. Can anybody tell me why this outputs: Ros? (My locale is: en_US.UTF-8 and I'm using gcc)
2. I need wchar_t if I want to use chars with accents ?
3. Can I use UTF-8 with wchar_t ?

According to Valgrind, your code has a memory leak:

==31733== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 8 from 1)
==31733== malloc/free: in use at exit: 15 bytes in 3 blocks....

Why when using realloc, john is reversed 3 times but not the other 2 names ? But if I use malloc, then the 3 names are reversed correctly ? (but then there is a memory leak)

How can I reverse all...

Thanks. Yes, actually according to the man page, %i has a different meaning according to the context. Therefore, just use %d instead.

How can I separetely extract the string and int after "dribble" ? (sscanf must limit TEXT to 9 chars to avoid buffer overflows.)

How come this code does not work with "dribbletext08" but does with...

Ok, I finally got it.

original[2] is an ampersand but replacement[2] also has an ampersand. So what was happening was that the while loop was replacing the replacement as well.

Solution:
move...

char original[15][7] = { "\u00E7"/*ç*/, "\"" , "&" ...

I tried to compile it explicitly stating UTF-8:
-std=c99 -finput-charset=UTF-8 -fexec-charset=UTF-8 -fwide-exec-charset=UTF-8

I tried using Hex codes as you suggested but only Unicode codes are...

Here is a C function that replaces some non-ASCII chars to html decimal entities. It seems that the char "ç" does not get replaced correctly but the rest do. Any idea why this is happening ?
