C++ (Cpp) Get_interrupt_state Examples

Example #1

File: circ_buffer.c Project: ralphxyz/Playing-with-AT90USBKEY

bit circ_buffer_put_nbytes(circ_buffer_t *b, uint8_t *bytes, uint16_t *n){
  uint16_t n_actual = 0;
  bit ret = PASS;
  uint8_t int_state = Get_interrupt_state();
  Disable_interrupt();

  while(b->num != b->size &&
          n_actual < *n){
    b->buf[b->end] = bytes[n_actual];
    b->end = b->end + 1;
    if(b->end == b->size)
      b->end = 0;
    b->num = b->num + 1;

    n_actual++;
  }

  if(n_actual < *n){
    ret = FAIL;
  }

  *n = n_actual;
  if(int_state != 0)
    Enable_interrupt();
  return ret;
}

Example #2

File: power_drv.c Project: garyStofer/USBjoyHost

{
   U8 save_int=Get_interrupt_state();
   Disable_interrupt();
   CLKPR=(1<<CLKPCE);
   CLKPR=x;
   if(save_int) { Enable_interrupt(); }
}

Example #3

end:
  if(int_state != 0)
    Enable_interrupt();
