INTERFACE LEVEL

35       The  functions  described  here are obsolete. For the inb(), inw(), and
36       inl() functions, use,  respectively,  ddi_get8(9F),  ddi_get8(9F),  and
37       ddi_get8(9F)  instead.  For  repinsb(),  repinsw(),  andrepinsl(), use,
38       respectively, ddi_rep_get8(9F), ddi_rep_get8(9F), and  ddi_rep_get8(9F)
39       instead.

PARAMETERS

42       port     A valid I/O port address.
43
44
45       addr     The address of a buffer where the values will be stored.
46
47
48       count    The number of values to be read from the I/O port.

DESCRIPTION

52       These  routines  read  data of various sizes from the I/O port with the
53       address specified by port.
54
55
56       The inb(), inw(), and inl() functions read 8 bits, 16 bits, and 32 bits
57       of data respectively, returning the resulting values.
58
59
60       The  repinsb(), repinsw(), and repinsd() functions read multiple 8-bit,
61       16-bit, and 32-bit values, respectively. count specifies the number  of
62       values  to  be read. A pointer to a buffer will receive the input data;
63       the buffer must be long enough to hold count values  of  the  requested
64       size.
65

RETURN VALUES

67       The  inb(),  inw(),  and inl() functions return the value that was read
68       from the I/O port.
69

CONTEXT

71       These functions may be called from user, interrupt, or kernel context.
