Application initialization.

Hi friends,

I am trying to make an application. I want my application to be
started as soon as the shell gets activated. That is it has to start
by itself rather than me giving the name at shell. For this which
configuration file did I have to change and where.

Thanks in advance.

With regards,

Rajneesh

Dear Rajneesh:
Have a look at usrConfig.c. In that file is a routine called usrRoot.
The very last statement in that subroutine goes:

#ifdef INCLUDE_USER_APPL
/*Startup the users application*/
USER_APPL_INIT /*must be a valid C statement of block */
#endif

This is the traditional place to put startup user code in a vxWorks image.
What I usually do is to define USER_APPL_INIT in config.h and either add a
subroutine call in place of USER_APPL_INIT in usrConfig.c or #define
USER_APPL_INIT to be a function pointer.

There are other ways, and some of them are more elegant with the GUI Tornado
interface and I am sure someone else will comment on that nuance.

Good Luck
Charles

Hello,

If you are using Tornado & projects, check out section 4.4 in the
Tornado User’s Guide: Creating a Bootable Application. That describes
how to make the application run automatically at boot time from a
project.

For the command line/BSP oriented method, read this tech note:

http://www.windriver.com/windsurf/appnotes/ide/tornado/t2/APN43/WTN43…

(you’ll need a WindSurf account to access this information).

HTH,

John…

Hi,

do the following
1. create a bootable application
2. include your main function (i.e the function name you will type in
shell) in the file usrAppInit.c like that of the following assuming
your application starts with the function main().

void usrAppInit (void)
{
#ifdef USER_APPL_INIT
USER_APPL_INIT; /* for backwards compatibility */
#endif

main(); /* add application specific code here */
}

then your app will be invoked automatically when ever you boot
vxworks.

main() …?

are you sure it will work? EABI prohibits main as a application function
name …

It will work if your main() function is inside a C language source file. There may be problems if you put your
main() function inside a C++ source file (which is probably why it is prohibited).

Hi,

I just showed that for example.

what ever is your function name you just enter within usrAppInit
routine and then compile. like,
void usrAppInit (void)
{
#ifdef USER_APPL_INIT
USER_APPL_INIT; /* for backwards compatibility */
#endif

function_name(); /* add application specific code here */
}
