Synopsis

void (*interruptf(int sig, void(*func)(int))) (int);
void (*interrupts(int sig, void(*func)(int))) (int);
Description
These functions are Analog Devices extensions to the ANSI standard.
The
interrupt

The different variants of the
handler dispatching functions. The variants will be appropriate for some
applications and provide improved efficiency. The default
function dispatcher saves and restores all scratch registers and modes on
the data stack around a call to the handler (
rupt. This dispatcher will pass the interrupt ID (for example,
to the handler as its parameter.
The
interruptf
switches between primary and secondary register sets to save and restore
registers instead of using the data stack. The
be used in applications where nested interrupts are enabled. This interrupt
dispatcher will pass the interrupt ID to the handler as its parameter.

registered and to call that handler. The handler passed as input to
