<INTEGRITY RTOS> Passing arguments to an entry point function of the CreateTask() task kernel call

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

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
