Function - Write a sequence of bytes "inband" to a device object.
#include<device/device.h (device_write_inband)> kern_return_t device_write_inband (mach_port_t device, dev_mode_t mode, recnum_t recnum, io_buf_ptr_inband_t data, mach_msg_type_number_t data_count, io_buf_len_t io_buf_len_t); #include<device/device_request.h> kern_return_t device_write_request_inband (mach_port_t device, mach_port_t reply_port, dev_mode_t mode, recnum_t recnum, io_buf_ptr_inband_t data, mach_msg_type_number_t data_count); kern_return_t ds_device_write_reply_inband (mach_port_t reply_port, kern_return_t return_code, io_buf_len_t bytes_writte);
The device_write_inband function writes a sequence of bytes to a device object. The meaning of recnum as well as the specific operation performed is device dependent. This call differs from device_write in that the bytes to be written are sent "inband" in the request IPC message.
Only generic errors apply.
Functions: device_write, device_reply_server.
