Create a switch (type 1) element
#include <audio_driver.h> ado_mixer_delement_t *ado_mixer_element_sw1 ( ado_mixer_t *mixer, char *name, uint32_t number_of_switches, ado_mixer_delement_control_sw1_t *control, void *instance_data, void (*instance_free) (void *data) );
The prototype is:
int32_t control( MIXER_CONTEXT_T *context, ado_mixer_delement_t *element, uint8_t set, uint32_t *bitmap, void *instance_data );
If you need to access this instance data, you have to call ado_mixer_get_element_instance_data() because ado_mixer_delement_t is an opaque data type.
The ado_mixer_element_sw1() convenience function automates the creation of a switch (type 1) element. A switch type 1 element represents a switch with a single input and output that can be open or closed by a single control.
A pointer to the newly allocated switch (type 1) element.
