xTaskGetSchedulerState API and isr

Posted by PENELON on January 30, 2013
Hello,

Is it safe to use xTaskGetSchedulerState API from an ISR handler ? No mention of that is done within the documentation.

Thanks

The general rule is "only API functions that end in 'FromISR' can be called from an ISR".

As it happens, I have just checked and it is safe to call xTaskGetSceduelrState() from an ISR, but that is co-incidence only.

Regards.

I did hope so,

Maybe an add can be done in documentation and/or API because it was necessary to me to know scheduler state before using xQueueSendToBackFromISR().

Regards

It causes HardFault in ARM Cortex-M3 MPU port. So it would be nice to have xTaskGetSceduelrStateFromISR() function.
