raccoon starts a Symbian application

[jmv_]

Hello,

I want the server raccoon starts a Symbian application when receives a HTTP request, is possible?

Thank you!

Sure you can.

Using Python you should (should, because I havn't tried it) be able to start another application using e32.start_exe(). From a native Apache module it can definitely be done.

However, if you want to use that other application in a CGI kind of way, so that the external application generates HTML and the communication is handled by reading/writing from/to stdout/stdin, some modifications might be needed.

Hi!

Which is the easier form to do it? is some example available?
I don´t know how to begin...

Thanks!

Why don't you start by telling what you want to accomplish

That might make it easier to say where to begin.

ok, the idea is:

I have a Symbian application that sends SMS to some contacts registered in a file, then I want the server, raccoon, starts this application when recives a HTTP request.

Thanks!

Do you have the source-code of that application? In that case, the best approach is probably to factor out the functionality you are interested in, and then create a custom Apache module that does exactly what you want.

What kind of application is it? Does it have a GUI?

It's a "console" application.
I have done it thinking about that it worked in background.

Thanks!

In that case you have alternatives; the program can run all the time as a server that the Apache request handler contacts using some IPC mechanism, or then you can invoke the program as the result of a HTTP request.

I assume you are using OpenC? Check 'Open C Documentation' -> 'Developer Guides' -> 'Threads,Processes,IPC, and Synchronization' for documentation on what kind of IPC mechanisms you have available. And check out posix_spawn for how to start an executable.

Hi!
I have been reading the documentation but I do not know how beginning the code… You know if there is some similar example that can serve me to begin?

Thanks again!

I'm sorry, I don't have any ready example available.

Hi!
The function:
int posix_spawn(pid_t * pid, const char * path,
const posix_spawn_file_actions_t *file_actions,
const posix_spawnattr_t * attrp,
char *const argv[], char *const envp[]);

The argument "const char * path", what kind of file can execute? a .sis file, a .exe file,...? I would like execute a "console" application, but I don´t know how to install it in my phone, I use Carbide and I don´t have a .sis of my application, only a .exe that I can run in the emulator when I do double click.

Thank you!

An executable file, but remember that on S60v3.0 you can only execute files that reside in the directory c:\sys\bin

I would like execute a "console" application, but I don´t know how to install it in my phone, I use Carbide and I don´t have a .sis of my application, only a .exe that I can run in the emulator when I do double click.

You have to create a SIS-file, because only the installer can put a file to c:\sys\bin. Check from the documentation and the examples included with the S60 SDK how to do that.

Hi!
I tested the function posix_spawn to see if it can run an console application (SendSMS). I created a new project in Carbide, it creates a default console application: Hello World!.

The code is:

// Include Files

#include "StartApp.h"
#include <e32base.h>
#include <e32std.h>
#include <e32cons.h> // Console
#include <spawn.h>

// Constants

_LIT(KTextConsoleTitle, "Console");
_LIT(KTextFailed, " failed, leave code = %d");
_LIT(KTextPressAnyKey, " [press any key]\n");


// Global Variables

LOCAL_D CConsoleBase* console; // write all messages to this


// Local Functions

LOCAL_C void MainL()
{
//
// add your program code here, example code below
//
console->Write(_L("Hello, world!\n"));
pid_t* pid;
const char* path="..\\..\\Epoc32\\release\\winscw\\udeb\\SendSMS";
const posix_spawn_file_actions_t* file_actions=NULL;
const posix_spawnattr_t* attrp= NULL;
int result = posix_spawn(pid, path, file_actions, attrp, NULL, NULL);
}
....
....

That path is where I have the executable of the application I want to start, that is if I do double click it running on the emulator. But I do not think that it is ok ...

Additionally, the application does not compile, the error is:
Undefinied symbol: '_posix_spawn' referenced from 'void mainL(void) (?MainL@@YAXXZ)' in StartApp.cpp:45
Where I invoke the function posix_spawn.

Thanks again!

Probably not - just use SendSMS.exe. That should do the right thing on the emulator and on target.

Additionally, the application does not compile, the error is:
Undefinied symbol: '_posix_spawn' referenced from 'void mainL(void) (?MainL@@YAXXZ)' in StartApp.cpp:45
Where I invoke the function posix_spawn.

Have you added the library libc.lib?

Hi!

I have solved the problem of compilation, it was by the library libc.lib. However, the application does something rare:
- Displays Hello World! If you do not write the function posix_spawn but if I write the function does not show Hello World! and it does nothing in the emulator.
- I believe that the parameters of the function posix_spawn are not properly (I think the path) but anyway it should print Hello World! because the code is before the function posix_spawn...

LOCAL_C void MainL()
{
//
// add your program code here, example code below
//
console->Write(_L("Hello, world!\n"));

pid_t pid;
const char* path = "..\\..\\epoc32\\release\\winscw\\udeb\\SendSMS.exe";
posix_spawn(&pid, path, NULL, NULL, NULL ,NULL);
}

The file SendSMS.exe that I want the function started is in this path, here is where Carbide save it to try it in the emulator ...
I searched on the Internet but did not find examples of the use of the function posix_spawn in Symbian ...
I don't know what can I do...

Thanks!!
