Reading UTF16 input from STDIN using fgetws()

2009-10-09T08:12:58Z

Hi all,
I am trying to read UTF16 input from STDIN using fgetws() on LINUX.

man pages of fgetws() says,
fgetws() converts the input string from the encoding either specified by "LC_CTYPE" or specified in fopen() to wide character string.

My intention is to read UTF16 input from STDIN not from a file. For this i will not use any fopen() because the input is direct from STDIN.

So i will use direct "STDIN" in fgetws() like
fgetws(buf,count,stdin);

As deault LC_CTYPE value is "utf-8" on linux (also on all unix flavours), fgetws() is treating the input as utf-8 and trying to convert to a wide character string.

My input contains UTF16 strings and it has "0xfeff" BOM as first character.
As fgetws() treating the input is in utf-8, 0xfe(first byte of BOM) will be an invalid sequence in utf-8 and also 0xff (second byte of BOM) is an EOF. So fgetws() is returning nothing.

If i use fopen() then there will be no issues because i will pass the input ecnoding as parameter to fopen() like fopen("filename","r,ccs=UTF16-LE");

With this fgetws() will treat the input as UTF16 and will convert the input from UTF16 to a wide character string.

So no issues with fopen().

But my requirement is input from STDIN.

Please let me know how to set the encoding "ccs=UTF-16LE" to STDIN so that fgetws() will consider the STDIN input in UTF16 form.

I have also tried fdopen() but no use.
fdopen(int fd,mode);

There is a requirement that the mode parameter vaues in fdopen() should be the same as of the one used in fopen().

But we are not at all using fopen() and the default encoding of STDIN is utf-8.
So when fdopen(fd,"ccs=utf-16le"); is used, it returns nothing as there is a mismatch in encodings i.e defualt of STDIN is utf-8 and fdopen is passing utf-16LE.

So please let me know how to change the encoding of STDIN i.e how to set encoding "ccs=UTF-16LE" to STDIN

In windows, we hava _setmode() but in LINUX no such provision because LINUX will treat text & Binary files as same.

Thanks in Advance.

Srikrishna Erra.

Hi,

I need to convert a windows ANSI test file to unicode in Linux. Later the

how compiler decide the range of real numbers in C...

2009-07-30T10:33:25Z

Say 16 bit compiler (for ex Turbo C) uses 2's compliment to find the range of signed integer.
Say for 16 bit n=16. Now applying 2's compliment equation : -2^(n-1) to 2^(n-1) -1
so for n=16 : The range is -32768 to 32767

This is ok. The question arises when it tell about real constant's range.
For 16 bit compiler the range of real constant is : -3.4e38 to 3.4e38

How they arrived to this real constant range?

Can any one share the mathematical calculation behind it?

malloc interposition how?

2008-07-16T20:55:19Z

I'm trying to do these things simultaneously:

use glib
use gc (Hans-Boehm)
use my own library of random code

I dont want to have to do manual garbage collection at least in the prototype stage.

However, I haven't found a way to link the above together that works.

I use the set_vtable function in glib to hopefully make it use the GC_malloc etc. from gc

I include fcnts malloc/free/realloc in my library and the compiler/linker doesn't complain
(presumably libc contains some special goop to not complain about these getting redefined
in client code). My malloc etc. of course just call GC_* fctns.

I believe I have all the right -I -L -Wl,-rpath etc. crud.

When I look at bins and my .so file with ldd everything appears to look for the correct libraries.

When I use nm on my .so I see symbols like malloc supposedly in the text secion (marked with T).

When I step with the debugger and a breakpoint in malloc (or realloc etc.) I always end up in the malloc
in my library, not the system malloc.

And yet, the program always seg faults eventually in a GC_malloc.

Any ideas what I'm missing, or is the whole approach somehow fatally flawed?

I've also tried using --wrap linker option, but it seemed to only map function defined in the source files being linked and
didn't affect the use of malloc etc. by depended-on libraries (I ultimately need this to work for gsl (GNU scientific library as well not only glib which provides the set_vtable functionality).

Thanks,
Britton

Shared Memory using threads in C on AIX

2008-06-18T02:59:35Z

I am looking for C program source code. Could you please help me in finding the source code of the required mentioned below.

Task that I need to complete:

Write a program to create multiple threads (one master thread and rest worker threads) and using the threads write into and read from shared memory

Restrictions:

Only one thread should be able to read at any instant of time into shared memory region.

Only one thread should be able to write at any instant of time into shared memory region.

Worker threads should inform the master thread after every read and write operation.

Master thread inform the worker thread (which is waiting to acquire shared memory region) that read or write operation is successful and it can acquire the memory for either reading and writing operations.

how to call Functions implemented in other file?

2008-05-27T06:06:24Z

hello!

i have a problem using gcc c Complier in Unix.
I want to use a function which is implemented in a file in another path.This function is written by the distirbuters of the system and so the system uses this function.But i want to use that in order to do one part of my homework.
Because the file that contains this function is *.c and not *.h, adding #include *.c to my code,generates problem..

any help??thanks!

NAN and complex.h

2007-09-18T15:52:08Z

Hi I made a program which basically averages data from a file. The data is stored as complex float and I'm reading it with fread with no problem. Some data are taged as NAN (at least ENVI, an image procesing soft read these values as NAN). If I average the whole data adding a number with a NAN gives me a NAN and my whole program fails.

What I did is the folowing which doesn't seems to work:

if(cabsf(zhhzhh)!= NAN)
{
printf("%f\n", cabsf(zhhzhh));
}

For some reason the test seeams to be positive all the time, I keep printing NAN's ("nan" actualy).

Any idea?

Jonathan,

maybe "kmod" is what you're looking for. kmod performs background
monitoring and makes sure the required modules are loaded by modprobe
as soon as the respective functionality is needed in the kernel, but
it is not designed to unload modules automatically.

Simply activate the option 'Kernel module loader' (CONFIG_KMOD) in
the kernel configuration. It is available for both Kernel versions
2.4 and 2.6, respectively.

\Steve

and I make a call to socket() requesting a IPPROTO_SCTP socket it will
fail with EPROTONOSUPPORT. Is there a way in some sort of kernel

For a start, the side which creates the message queue (probably the
server) needs to set the permissions, e.g.:

#include <sys/stat.h>
...
toinput_id=msgget(key_out, IPC_CREAT|S_IRUSR|S_IWUSR);
...
tooutput_id=msgget(key_in, IPC_CREAT|S_IRUSR|S_IWUSR);

Otherwise, access will be refused, hence EACCESS.

Some other issues:

The third argument to msgrcv() needs to be the size of the buffer,
e.g. sizeof(text) not strlen(text).

The return value from main should be non-negative, zero for success
and greater than zero for failure. In practice, a value of -1 will
typically result in an exit code of 255 due to being truncated to 8
bits.

Grinning stupidly, the barman got up from his stool. ' B-b-but . . .'
he stammered, hiccupping, ' if they vanish again . . . what then? '
'H'm,' said the professor thoughtfully. ' In that case come back and
see us. Delighted to have met you. . . .'
At this Koroviev leaped out of the study, clasped the barman's hand and
shook it violently as he begged Andrei Fokich to give his kindest regards to
everybody at the theatre. Bewildered, Andrei Fokich stumbled out into the

A buzzing crowd collected, discussing the incredible scene. It was of
course an abominable, disgusting, thrilling, revolting scandal which only
ended when a lorry drove away from the gates of Griboyedov carrying the
unfortunate Ivan Nikolayich, the policeman, the barman and Ryukhin.
At half past one in the morning a man with a pointed beard and wearing
a white overall entered the reception hall of a famous psychiatric clinic
recently completed in the suburbs of Moscow. Three orderlies and the poet
Ryukhin stood nervously watching Ivan Nikolayich as he sat on a divan. The

Hello!
I am Zinaida. To talk about my personal qualities I`l try to look at
myself from aside. So I`m a romantic, charming, feminine, and sweet
girl. Yet as a person I am open-minded, easy-going, kind-hearted. From
the very beginning I try to behave naturally. I dislike lie and
hypocrisy. Kindness and decency are the qualities that are very
important for me and that`s why I value them in myself. I love my
parents very much as they have given much to me and I am grateful to
them.
I have some questions for you if you want to get to know me closer:
* Are you planning to visit Russia?
* Have you ever been to Russia?
* Would you like to correspond or to talk by phone?
* What is important for you in relations and am I right for you?
* Are you interested in serious relations with Russian woman?
* Why are you interested in Russian lady?
I will be waiting for your reply to

Hope you will tell me about yourself,

Re: Core file size?

2006-12-01T07:46:02Z

This patch fixed it.

http://lkml.org/lkml/2005/6/13/204

The ELF core dump code has one use of off_t when
writing out segments. Some of the segments may be
passed the 2GB limit of an off_t, even on a 32-bit
system, so it's important to use loff_t instead. This
fixes a corrupted core dump in the bigcore test in
GDB's testsuite.

The relevant function seems to be maydump() (in binfmt_elf.c); this
determines whether or not a given VM area should be dumped.

Essentially, it doesn't dump data which can be obtained elsewhere,
e.g. from an executable, shared library, unmodified mmap()d file, etc.

Primarily, this prevents dumping the .text and .rodata segments of the
executable and shared libraries, which will often account for most of
a process' address space.

Core file size?

2006-11-30T06:13:36Z

Does anyone know what determines the size of a core
dump? I have a process running out of memory (it
allocates about 3GB) - but the size of core varies
(between 2-3GB) depending on how much the process
wrote on the allocated memory.

Also, the time it takes to write the core (same size)
varies??

I briefly looked at elf_core_dump and get_user_pages()
in binfmt_elf.c. Is there any documentation on this?
Or anyone knows how it works?

TIA

If you don't feel like reading proc or want to make things more
portable, use libgtop.

It's documented in the proc(5) manpage, but I don't think it records
the heap size separately.

Probably the best option is to look in /proc/<pid>/maps for writable
segments with zero for the device and inode numbers (i.e. anonymous
maps).

Also, note that glibc's malloc can use explicit anonymous mmap() to
obtain memory, as well as sbrk(), so there isn't a monolithic "heap"
in the traditional sense.
