Like was previously mentioned, you may need to use memcpy().

_tcscpy_s and it's variants only guarantee that the string will be copied IF it fits. I suspect that the compiler "figured out" that it could safely optimize the copy using 32 or 64 bit chunks. This would result in satisfying the condition that the string be null terminated, but would also end up copying random data stored after the original string.

I am learning how to use ellipsis in function.
Started with putting "int" as parameters, with first entry being count of parameters passed to he function.
Now I want to pass multiple types , not just int , to the function.
The following snippet will do, but...
How do you get "type" from passing a char * - in this case "format" variable?
What did I missed ?
Thanks for your help.
Vaclav
I am not sure if I tagged the code properly.
<pre lang="c++">
void my_printf( char *format, ... ) {
va_list argptr;
va_start( argptr, format );
while( *format != '\0' ) {
// string
if( *format == 's' ) {
char* s = va_arg( argptr, char * );
printf( "Printing a string: %s\n", s );
}
// character
else if( *format == 'c' ) {
char c = (char) va_arg( argptr, int );
printf( "Printing a character: %c\n", c );
break;
}
// integer
else if( *format == 'd' ) {
int d = va_arg( argptr, int );
printf( "Printing an integer: %d\n", d );
}
*format++;
}
va_end( argptr );
} </pre>

That code looks like it should broadly work, but you are assuming any 's', 'c', or 'd' in the string is a format identifier. Your main loop should iterate the characters of the format string, copying them to the output until you see a format specifier. When you see a '%' character then you know that is the start of a formatting sequence so you need to get the width, precision and type details. Once you have extracted all those values, then you can process the next argument according to the type field character.

My feeling exactly.
I this whoever posted the code missed something.
Here is their sample use of the function.
int main( void ) {
my_printf( "sdc", "This is a string", 29, 'X' );
return( 0 );
}
This code displays the following output when run:
Printing a string: This is a string
Printing an integer: 29
Printing a character: X
Now where is the "sdc" print?
And I thought that "format" was some kind of special feature.
I guess I ditch this, maybe I can figure out how to use templates.
Thanks

As per what Richard said READ THE MANUAL.
"sdc" is the format specifier for the three parameters that follow
s = STRING
d = Signed decimal integer
c = Character
"This is a string" they want displayed as a string
29 they want displayed as a decimal
X they want displayed as a character
Try changing changing "sdc" to "s%.3fc" and watch the output
%.3f is a complex format it means write value as a float to 3 decimal places.
So we still have 3 instructions s + %.3f + c
So the first string is a FORMAT STRING it tells the print function what to do with the following data passed in.

Thanks for reply, figured it out myself, but did not have time to reply.
As far as your first sentence goes, take a refresher course and read "how to answer the question".
You reply was great, but you do not have to be so snippy about it.
GOT MY POINT?
Have a swell day.

Yes, because threads can only exist within an executable program. However, your question or problem is far from clear.

Try this:
#include "stdafx.h"
#define _MT
#include <windows.h>
#include <process.h> /* _beginthread, _endthread */
#include <stddef.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#pragma comment(lib, "user32.lib")
#pragma comment(lib, "libcmt.lib")
#pragma comment(linker, "/NODEFAULTLIB:libcd.lib")
void ThreadFunction1(void *ch);
void ThreadFunction2(void *dummy);
BOOL repeat = TRUE;
int main(){
printf("\nMultithreading with two threads.\n\n");
printf("Thread Function 2 listens for key strokes. \n");
printf("Thread Function 1 does all the other work \n");
printf(" \n");
CHAR ch = 'A';
_beginthread(ThreadFunction2, 0, NULL);
while (repeat){
_beginthread(ThreadFunction1, 0, (void *)(ch++));
Sleep(1000L);
}
printf(" \n");
return 0;
}
void ThreadFunction2(void *dummy){
_getch();
repeat = 0;
}
void ThreadFunction1(void *ch){
while (repeat){
Sleep(100L);
}
_endthread();
}

yes i use 20-30 threads if i use more i receive errors,nsock timeouts! nsock errors! etc...so i need to put that code somewhere but i don't know how?

And you think maybe we can guess? We have no idea what your code is supposed to be doing, or what you are trying to achieve with these threads.

ncrack -vv -d7 --user admin -P list1.txt 81.196.251.12:3389,CL=20,cd=320ms -oN good.txt -f
CL=means maximum threads 20 , becouse if i use more...i receive nsock errors
tools i use are ( ncrack +visual c++)

So you are trying a brute force attack on a site via the remote desktop access (port 3389) as user admin with a set dictionary of passwords, and you want us to help you??????
There is no good or legal reason you would need to do such a thing, so that leaves only illegal.
Not going to happen

Good to see you aren't stupid enough to be trying to develop something illegal and give up your own IP ... gratz you get a +1 for IQ in my books and the the authorities may not kick in your door one evening.

It sounds like you are wanting to know how to use a network authentication cracker.  How exactly is this a C / C++ / MFC question?
