[Dev-C++] popen

[Erik S. <esc...@gm...>]

Here is my code

#include <iostream>
#include <cstdio>
#include <string>
#include <fstream>

using namespace std;

int main(int argc,char *argv[]){

	FILE* pipe=popen("ls","r");
	
	string total;
	char c;
	
	cout<<"initialized"<<endl;
	
	while(!feof(pipe)){
	
		total+=fgetc(pipe);
		
	}
	
	fclose(pipe);
	
	cout<<total<<endl;
	
	return 0;

}

that code works, however, I am not trying to work with ls.  I am  
trying to work with "top"  when I replace ls with top, the program  
refuses to work

this is on a mac

thanx for any help

-Erik

If You anderstand German, there is a complete book dealing with this 
topic. Because technical German is similar to technical English, You 
might reed and understand it fairly well , I suppose. In my weak english 
translation it (the pocked book) could be titled "Reliable Apply of C 
Library Functions" if it where translated.

Helmut Erlenkötter
C Bibliotheksfunktionen sicher anwenden.

(c) Rowohlt Taschenbuch Verlag 2003
415 pages cost 12,90 Euro

(It is from the "rororo Taschenbuchreihe Grundkurs Computerpraxis")

You also could use GOOGLE to find a lot of tutorials dealing with C 
Library headers and functions in the web, for example:

Re: [Dev-C++] File operations

[Per W. <pw...@ia...>]

Since you are using the strtok() function (a not too much liked function
by the way, since it modifies the string), I assume that you are writing
in C.

Either use atoi() or strtol() to convert from string to number.

Note that atoi() breaks at first non-numeric character, so in case you use
it with a string that doesn't contain a number, you must manually check
the contents of the string.

strtol() will set a pointer to the first non-converted character, which
helps when continuing the processing of the string.

[Dev-C++] File operations

[KrowniX \(\)--\(\) <kr...@ya...>]

Hi ...

Hey..today I got some other problem that you may help-me...I am working to use the response of the ping command to do some operations....for example:

Resposta de 10.0.0.1: bytes=32 tempo=49ms TTL=250
Resposta de 10.0.0.1: bytes=32 tempo=48ms TTL=250
Resposta de 10.0.0.1: bytes=32 tempo=48ms TTL=250
Resposta de 10.0.0.1: bytes=32 tempo=49ms TTL=250

I already know the function strtok() in string.h that allowed you to cut the file as you want...and i don´t have problems to separate the "tempo=49ms" from the rest of the file..so..that´s my question..

the strtok() function returns a char*, and I need to use that number "49" to make some basics operations like > < .;...really simple.. but I am not been able to do the conversion of char* to int...

Does anyone know how do I do this??

Thanks....and if I found out I´ll post it here..

When I began, I too used books! But unfortunately, they were local ones 
(from India). I would recommend Thinking In C++ by Bruce Eckel if you 
were doing C++. For a beginner in C, I think the best way to get what 
you want is to simply dive into the header files in the include

[Dev-C++] Any Manual?

[Tudorache D. <str...@ho...>]

Hi,

Is there a Dev C++ manual with a COMPLETE description of the C functions in 
Dev C++. of the libraries, which functions are contained in which header 
files?

Thank you very much in advance!

Re: [Dev-C++] FILE*

My mistake :(

The (int fd) constructor was only available as a non-standard extension
in the old fstream classes.

[Dev-C++] FILE*

[Erik S. <esc...@gm...>]

I was told to use fileno and an fstream constructor to convert a  
FILE* to an fstream.

I'm trying to do this on a mac, here's the ode that failed:

#include <iostream>
#include <cstdio>
#include <string>
#include <fstream>

using namespace std;

int main(int argc,char *argv[]){

	fstream pipe(fileno(popen("ls","r")));
	
	string total;
	char c;
	
	cout<<"initialized"<<endl;
	
	while((pipe.get(c))!=NULL){
	
		total+=c;
		
	}
	
	cout<<total<<endl;
	
	pipe.close();
	
	return 0;

}

any ideas why this doesn't work

You request invalid permissions for the pipe. The code should be

FILE* pipe=popen("top","r");

Then you can read from that pipe.

This code is for a mac

why does this not work?

#include <cstdio>
#include <fstream>

using namespace std;

int main(int argc,char *argv[]){

	FILE* pipe=popen("top","top");
	
	ifstream pipeStream(fileno(pipe));
	
	string total;
	char c;
	
	while((pipeStream.get(c))!=NULL){
	
		total+=c;
		
	}
	
	cout<<total<<endl;
	
	pipeStream.close();
	
	return 0;

}

Re: [Dev-C++] popen

[Per W. <pw...@ia...>]

It is not part of any standard library.

However, google "popen for windows" gives a number of links to ports of
the function".

[Dev-C++] send()/recv() SMTP commands

[KrowniX \(\)--\(\) <kr...@ya...>]

Hi,

I ´m having trouble in send() and recv() smtp commands, I already write my code, and there´s no error, and works without problems but I still don´t send e-mails...
I´m posting my code here, could you take a look a maybe tell me where I´m wrong?

If someone need the .dev file to try help me, let me know that I will send it to you.

Bye, 

Krownix

Re: [Dev-C++] using __asm list

[Per W. <pw...@ia...>]

All external C symbols have a leading underscore, i.e. from assembler, the
function is called _printf.

Are you planning to write device drivers for embedded systems? If not -
exactly why do you bother with learning assembler?

First of all, it is very hard to write more efficient code than a modern
compiler generates.

Then, you have to realize that different compilers uses different syntax
for the assembler code.

Also, different compilers have different calling conventions and layout of
memory objects. For C++, the name mangling differs between compilers and
even between different versions of the same compiler.

Finally, there are quite a number of other processors than the x86 series,
and most code that requires assembler routines are _not_ run on x86
machines.

[Dev-C++] using __asm list

[Noorez K. <lor...@ho...>]

I'm trying to learn how to use the __asm. Hear is something that i was 
trying to learn from:

#include <stdio.h>


char format[] asm("format") = "%s %s\n";

char hello[] asm("hello") = "Hello" ;

char world[] asm("world") = "world";


int main( void )

{
   __asm

   (

      "mov  eax, offset world;"
      "push eax;"
      "mov  eax, offset hello;"
      "push eax;"
      "mov  eax, offset format;"
      "push eax;"
      "call printf;"

      //clean up the stack so that main can exit cleanly
      //use the unused register ebx to do the cleanup

      "pop  ebx;"
      "pop  ebx;"
      "pop  ebx;"
   );

    return 0;
}

The compile error is that it could not find printf. How do make the printf 
function visible to the asm code?.

And one more question... I all other tutorials i've seen, when examples of 
inlining assembly are shown, they are shown with braces{} and not (). When I 
compile, i need to use () for it to work.
Is there something i'm missing here...?

Re: [Dev-C++] FILE*

[Per W. <pw...@ia...>]

fstream has a constructor taking a file descriptor.

You can retrieve the file descriptor from a FILE by use of the
fileno(FILE*) function.

One reason for interfacing FILE and a C++ stream is if the C++ code makes
calls to an existing C library. However, great care has to be taken to
vaoid problems with cached data when switching between C and C++ access
methods for an open file.

i am writing a program where i want one of my tasks is to call values from an n sized array in batches of 100 values to be used as single values in another array.
1. how do i call the values until i reach the end of the array when i do not know the size of the array.
2. how do i get only the values in the first dimension of the array, that is i tobe put into surface 1 with values for the 2nd dimension being left out, where surface1 is given by the summation of the first valuees of array tempa, that is values from i, surface is given by values of the summation of the power of values incremented by j                  
                  surface1 = surface1 + pow(tempa[i][j], 2);//surface1 summation
                  surface = surface + pow(tempa[i][j], 2);//surface2 summation
                  denominator = surface1*surface;
