How to distinguish if a function runs in a Task/SWI/HWI

Sebastian D.

Hi,

I've a function for error handling, that does some System_printf(). It is called from various Tasks and HWIs. I'm using SYSStd what does not work on HWI and SWIs, therefore I want to check if it is running on a Task.

Is there a function to distinguish in what content a function is executed?
Is something like that working:

if(Task_self()==NULL)
{
//HWI or SWI
}else
{
//Task
}

I'm using SYS/Bios 6.33.06.50 with CCS 5.2 on a C6670

Thanks,

Sebastian

Sebastian,

The BIOS module provides an API for this: BIOS_getThreadType().

It returns a 'BIOS_ThreadType' enumeration with one of the following values:

        BIOS_ThreadType_Hwi,         /*! Current thread is a Hwi */
        BIOS_ThreadType_Swi,         /*! Current thread is a Swi */
        BIOS_ThreadType_Task,        /*! Current thread is a Task */
        BIOS_ThreadType_Main         /*! Current thread is Boot/Main */
