=============
INTEGRITY RTOS
=============
Task kernel calls CreateTask(), CommonCreateTask(), CreateANSICTask(),
CreateProtectedTask() contain several arguments. One of them is the
entry point function.

Can that (entry point) function have arguments? How to pass these
arguments to the entry point function while calling CreateTask() and
similar task kernel calls.

I have never used Integrity RTOS but I'm sure the answers to your questions
are very easy to find in the manuals and examples that surely come with your
purchase. You do have the manuals?

I would be very surprised if the answer to your question "Can that function
have arguments" was "no".

Regards,
Richard.

No, it can't have arguments. But you can associate an address with the
task using Get/SetTaskIdentification; that address can point to a
structure containing the arguments (like in Win32 or pthreads, where you
also can pass a single pointer only, not arbitrary arguments).

Thank you.

It works quite fine.

Here is an example:

====== foo.c ======
/* INTEGRITY RTOS */

#include "INTEGRITY.h"
#include <stdio.h>

void CHECK(Error TheError)
{
if (TheError) HaltTask(CurrentTask());
}

void entry_point()
{
Address TheAddress;
Error TheError = GetTaskIdentification(CurrentTask(),&TheAddress);
if (TheError == Success)
{
printf("Success -> GetTaskIdentification returned %s\n", TheAddress);
}
else
{
printf("Failure -> GetTaskIdentification returned Error=%d\n",
TheError);

}
Exit(0);
}


int main()
{
Task task;
char* ptr = "ABCDXYZ";

CHECK (CreateProtectedTask(1, (Address)entry_point, 0x1000,
"the-task", &task));
CHECK (SetTaskIdentification(task, (Address)ptr));

CHECK (RunTask(task));

exit(0);
}


===================



===== Output ======

Success -> GetTaskIdentification returned ABCDXYZ
