C++ (Cpp) fault_handler Examples

Example #1

File: setup.c Project: antonio-fr/trezor-mcu-hid

void nmi_handler(void)
{
	// Clock Security System triggered NMI
	if ((RCC_CIR & RCC_CIR_CSSF) != 0) {
		fault_handler("Clock instability");
	}
}

Example #2

File: isr.c Project: bajdcc/MiniOS

void isr_stub(struct int_frame *r) {
    if (r->int_no < ISR_IRQ0 || r->int_no == ISR_UNKNOWN) {
        fault_handler(r);
    } else if (r->int_no < ISR_IRQ0 + 16) {
        irq_handler(r);
    } else if (r->int_no == ISR_SYSCALL) {
        syscall();  // get syscall number form proc->fm
    } else {
        panic("isr_stub: wrong interrupt number");
    }
}

Example #3

File: win32-fault.c Project: jes5199/mythryl

 * this is where win32 handles traps
 */
