Allowed system calls in ISRs

Fri May 27 12:57:11 UTC 2005

Hi,

section 6.3 of the RTEMS C users' guide lists system calls that
may be made from ISRs. Apparently this list is incomplete:
"Interrupt Manager" is missing completely while section 6.4.5
suggests that at least rtems_interrupt_is_in_progress() is
allowed in ISRs.

I'm specifically interested in rtems_interrupt_catch(): is
it allowed to change an interrupt handler while in an ISR?

Kind regards
