- read from an I/O port
#include <sys/ddi.h> #include <sys/sunddi.h> unsigned char inb(int port);
unsigned short inw(int port);
unsigned long inl(int port);
void repinsb(int port, unsigned char *addr, int count);

The functions described here are obsolete. For the inb(), inw(), and inl() functions, use, respectively, ddi_get8(9F), ddi_get8(9F), and ddi_get8(9F) instead. For repinsb(), repinsw(), andrepinsl(), use, respectively, ddi_rep_get8(9F), ddi_rep_get8(9F), and ddi_rep_get8(9F) instead.
A valid I/O port address.
The address of a buffer where the values will be stored.
The number of values to be read from the I/O port.
These routines read data of various sizes from the I/O port with the address specified by port.
The inb(), inw(), and inl() functions read 8 bits, 16 bits, and 32 bits of data respectively, returning the resulting values.
The repinsb(), repinsw(), and repinsd() functions read multiple 8-bit, 16-bit, and 32-bit values, respectively. count specifies the number of values to be read. A pointer to a buffer will receive the input data; the buffer must be long enough to hold count values of the requested size.
The inb(), inw(), and inl() functions return the value that was read from the I/O port.
These functions may be called from user, interrupt, or kernel context.
