Hi,
So I wrote code like this
but I have not what I expected for example I put parameter to my program argument to main here: 123456789123456 789
and ithe display is not this. why ?
Maybe the problem is on my way to use char * ?
Could you you help me please ?
Thank you
Kenzo...

Hi,
I have do that routine:
Is that good the way ?
ascii2binary (char* sourceAscii, char* destBin)
{
int64 lowPart = 0;
int highPart = 0;
for(int i=0; i<20; ++i)
{
lowPart += (sourceAscii[i]-48)*exp(10,i); //example= 10 exp 0 //corresponding to number 2 of 654342....Leave a comment:

Hi,
Not yet time to see quite for programming this routine :(
any help will appreciate :)
Thank youLeave a comment:

Ok,
I will try to do :)

Unfortunatly I'm using Kdevelop C++ in Linux
So I don't know how make this routine.
Could you give me an example code please ?
Thank youLeave a comment:

Yes I understand but when you writed atol you mean atoll I suppose for an _int64 ?
At time is it better to use long long int for atoll() or _int64 is too good as well for atoll()?
For the routine could you help me more ?
Thank youLeave a comment:

Sorry a little error occurs for this ;
is not 128 but 120.

Ok,
So if we consider we are in big endian.
using bit operators I will have:
So like you can see I can't fit all my array, with an _int64 I can fit only till array [7]. So like you said by using 2 _int64 I will fit the rest of my array like:
S if this way is correct, ok then next step (but in fact first step) is how store the encoded value (for example passed by arguments)...Leave a comment:

Hi,
For more details, it's about a data packet to send. this packet containt severals "FIELD NAME" with her "FIELD SIZE" and "REMARKS"
e.g:
...Code:[U]"FIELD NAME" | "FIELD SIZE" | REMARKS [/U] Sender ID | 4 bytes | identifies the source system to the destination system. ...

the problem is the size. I have a 16 byte array. and I must find a variable with 16 bytes too. Because the __int64 is only a 8 byte int and what must a store in the rest of my 8 bytes array?? I must use an integer which is more big than a simple _int64 for use efficiently the size.

Hi,
Sorry yes I try with memcpy() and it's ok cool.
But now my problem is to use a much bigger (size * 2) variable than the __int64 to fit correctly data into my 16 bytes array.
Thank youLeave a comment:

Hi,
i think that I tried too with memcpy() but anyway I will try again.
So what you mean when saying "..when there are two complements" ?
If I well understand I explained the fact that if it's possible to use a more big int type than _int64 so exactly a 16 bytes types for example I don't know "long double int" and to get contain of it into my 16 bytes char 'allmsg.number_ card[x]`' and how...Leave a comment:

Hi,
Thanks in fact the goal is that with some type of long long integer I must fit the entered value in exactly 16 bytes of char (or 128 bits) ... So I choice to use an _int64 but perhaps is there another type of long integer which is in 16 bytes just like may char array, and so with this one it will be more easy I think, could you advise me another solution ?
But for the moment, I use an _int64 and your solution with memcopy()...Leave a comment:

Thank you Savage,
Exactly, I want : the contain in _int64 must be the same (but in bytes) format in card_number[16] .
For example when I display containt of my variables:
Like you see long long int: 123456789 in hex is 75BCD15 (bytes 12 -> 15 )
but what is contain of byes 4 -> 7 ?? strange
I think that problems come before from here:
But I'm...Leave a comment:

Ok,
So for resuming all I wrote before.
I have this struct :
And I pass to allmsg.card_num ber an _int64 but it is not good way
Could you fix me please ?

how pass an __int64 to unsigned char [16]
Hi,
I have a struct "allmsg" and him member :
allmsg.card_num berCode:unsigned char card_number[MAX_CARD_NUMBER]; //16
And I must store contain of an __int64 into this member
Code:__int64 temp_badge_id; unsigned char *ptemp_badge_id; //
So I pass value to this last :
...Code:DLL_API(long)
No activity results to display
