thats right
Artöm
It is not. Globals make debug harder and multithreading a pain
Artöm
It should be defined as local to begin with
Artöm
Is it possible to make condition variable entirely local ib your case?
Artöm
It is a general rule of programming to make variables as local as possible

how does C or C++ fit this task? by the way, what you just sent looks like just a list of web terms to me :)

What's the purpose of volatile variables?!
Are they important in general?!
MᏫᎻᎯᎷᎷᎬᎠ
How does the compiler mark them as "this can be read outside the program segment", how does that accommodate with virtual addresses and so on?!

How does the compiler mark them as "this can be read outside the program segment", how does that accommodate with virtual addresses and so on?!
And does the compiler guarantee that this will be a true volatile variable and definitely can be read outside the program?!
Since they are so useful and important
Why the new standard is deprecating it in most places?!
MᏫᎻᎯᎷᎷᎬᎠ
Is there any system call for allowing that?
MᏫᎻᎯᎷᎷᎬᎠ
But
Is it guaranteed to be true volatiled or it's the same case like inline functions where the compiler will choose the best option
MᏫᎻᎯᎷᎷᎬᎠ
I don't know much about assembly
But i Guess it's the same case where instructions are being loaded to the memory and read from there
Also assembly sometimes uses some system calls(I think), it's not like there is another volatile keyword there
MᏫᎻᎯᎷᎷᎬᎠ
Yeah
System calls are not made from outer space or somewhat lol
But still assembly uses it
Last time I recall, you put the system call number into a specific register for execute

Madhu is so much great source of knowledge here
You don't wanna miss her presence
MᏫᎻᎯᎷᎷᎬᎠ
Nah
In general there is not
Assembly is a very platform-dependant language

Are there any catalogue for c/c++ free libraries? For example, I failed to google for doc format, so I created my own. But StackOverflow does not allow to publish name of my library, so its still hard to google library to extract text from doc format
Anonymous
I was just being an asshole
MᏫᎻᎯᎷᎷᎬᎠ
Okay
So you were just messing around

Alex
Did you open sourced the library?
yes, two libraries for doc and pdf. for doc I found nothing, for pdf low quality solutions for extracting text
Alex
so I created two libraries
Alex
gonna publish to catalog you provided
Alex
they are on github

Post the links please here

Well it's C, not C++
Try to find the same list of libs for C

its possible to use it for C++(actually I do it). I use extern "C" in header file
Anonymous

I mean if you can use it in C++ it doesn't make it Awesome C++ because a lot of (if not all) common practices in C language are considered bad ones in C++
Alex

ok, I will try to pull anyway, cause I did not find any free c++ solution to extract text from doc files
Alex
they can reject
Anonymous
You definitely should give a try
Alex
I am not sure, but format description is free. and linux utility cat2doc is free also
Alex
and what about libreoffice? it is possible to save document in doc format
Alex
I am talking about doc format, not docx. docx is easy to parse with XML lib
Anonymous
I dunno about DOC, but there's Apache Tika can which extract meta info about DOCX
But it's in Java
Alex
do you mean there is new version of doc format which is not compatible? do you have such document?
Alex
unfortunately I don`t use Windows
Alex
I will try to ask my friends for such document. thank you
Anonymous
Oki doki

Is it a binary format?
Alex
docx is xml. doc is binary
Anonymous
It sucks
Anonymous
Totally agree
Alex
do you mean doc, not docx? I created doc library several years ago and did not get any correct doc file which is impossible to read
Alex
also my library is used by chinese company
