Attach a handler function to an interrupt
#include <audio_driver.h> int32_t ado_attach_interrupt ( ado_card_t *card, int32_t irq, void (*handler) ( HW_CONTEXT_T *hw_context, int32_t irqnum ), HW_CONTEXT_T *hw_context );
The ado_attach_interrupt() function attaches a handler function to an interrupt. The handler function runs in user space, not in the kernel space.
The io-audio manager automatically detaches any interrupt handlers when your Audio HW DLL is unmounted.
0 on success, or a negative number if an error occurred (errno is set).
