I'm not sure I understood how it works.

The first character conversion prints whatever the buffer variable contains.
The second should print "0" padded with 18 zeros right?

Wouldn't that...

You are right. I fixed the title. Thanks.

Did I forget to specify that I need to do this in C(++)?

I need to right-pad with zeros a string by using (s)printf.

I looked up the manual and tried with

printf("%-19s", buffer);

which right-pad the string with spaces. So I tried
...

#include <stdint.h>

int64_t e uint64_t.

On a 32 bit machine it is usually defined as (glibc code)

typedef unsigned long long int uint64_t;


The compiler will probably use two registers...

Let's be good today :-)

No I haven't. You mean I should set LD_LIBRARY_PATH in the main executable to add
the relative path based on it's current directory? I'm not sure it'll work if the loader

Hi,

first of all I apologize if this is not the right section to post this question, but I didn't
know where else to post it.

I've developed an application which uses a shared library...

It looks like it worked.

Could you please explain or point me to an explanation of this?

Thanks,
S.

I'm sorry, but I don't get what you mean.

I've google a bit about this and couldn't find an answer. Actually I read that it can't be done.

Basically I've defined the following structure and typedef it as follows.

stuct Name {
};
...

There is nothing to recreate.

I m doing a sequence of

mkdir(dir);
chdir(dir)
for(subdir to create)
mkdir(subdir[i]);
chdir("..");

and so on, which in my case seems perfect, as I have to...

The best way is probably to iterate and call mkdir and chdir every time.
I'm actually in the process of doing something similar, and that's the way I'll go.
Constructing the (full) path every time...

Indeed. That's why I said I'll leave optimization as my last option.

First I'll make it fast and correct (hopefully bug free), then switch to optimization to make
it even faster (even if of a...

Do you have a _VERY_ good tutorial about profiling with gprof ? I'm actually having
some trouble finding one. I found many, but none that satisfies me.
I'm particularly interested in profiling...

Nice tip! Didn't think of that.
Thanks.

Although it's four functions and not only two. Thus means
two arrays of pointers.

Interesting solution anyway.

Yes.



Too easy! :-)
No, I don't have any control over it. Even because the packet is not always sent through actual IP protocol, but it could also be sent through USB.

It's an embedded...

Hi.

Problem: I have to parse the payload of a packet. The payload could be in Big Endian Format (network byte order) or little. That depends on a flag present in the header of the packet.

Hi,

The structure that will follow is supposed to hold the following RTP header field

0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8...

To be honest, I don't understand what you mean and how I should apply your suggestion to my case (for dumping the tables).

If possible, can you point to any interesting lecture with actual...

That's why I wouldn't want to use a database. The work involved, and the dependency produced, is not worth it in my case (IMHO).

I only have one writer, and one reader.

Data are written...

You mean I should use a database for holding the tables, like sqlite ?

Nope. I'm just trying to write an application as efficient as possible, that needs to dump indexes table, and I'd like to learn as much as possible from this experience.



Do you mean to execute...

Hi,

my application (actually library) indexes a file of many GB producing tables (arrays of offset and length of the data indexed) for later reuse. The tables produced are pretty big too, so big...

The only thing the spec report is that
16bit is 10bit Mantissa 5 exponent
32bit is 23bit Mantissa 8 exponent
64bit is 52bit Mantissa 11 exponent
128bit is 112bit Mantissa 15 exponent

and is...
