AVRC control callback function.

Parameters

[in]	handle	: Connection handle

typedef void( wiced_bt_avrc_msg_cback_t)(wiced_bt_avrc_msg_t *p_msg)

AVRC data callback function.

It is executed when AVCTP has a message packet ready for the application. The implementation of this callback function must copy the wiced_bt_avrc_msg_t structure passed to it as it is not guaranteed to remain after the callback function exits.

Parameters

[in]	handle	: Connection handle
[in]	label	: Message label
[in]	opcode	: Message opcode (see AVRC opcodes)
[in]	p_msg	: AVRC message
