Hello,
I was studing the gnumach sources and I found the following interface:
routine device_read(
device : device_t;
sreplyport reply_port : reply_port_t;
in mode : dev_mode_t;
in recnum : recnum_t;
in bytes_wanted : int;
out data : io_buf_ptr_t
);
But I don't understand why there are two arguments: recnum and bytes_wanted.
Only one of them is not enough? There is some documentation somewhere about
this system call?
TIA
