void libarm_restore_irq_fiq(int disable_irq_fiq_return);
disable_irq_fiq_return — The value returned from libarm_disable_irq_fiq.
This function restores the IRQ and FIQ enable state to the state it was in before a call to libarm_disable_irq_fiq.
Note that this function modifies the CPSR register's control field and therefore will only work when the CPU is executing in a privileged operating mode.
int s; // Disable IRQ and FIQ interrupts s = libarm_disable_irq_fiq(); … // Restore IRQ and FIQ interrupts libarm_restore_irq_fiq(s);
