inb(9F) 						   Kernel Functions for Drivers 						   inb(9F)

NAME
inb, inw, inl, repinsb, repinsw, repinsd - read from an I/O port SYNOPSIS
#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); void repinsw(int port, unsigned short *addr, int count); void repinsd(int port, unsigned long *addr, int count); INTERFACE LEVEL
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. PARAMETERS
port A valid I/O port address. addr The address of a buffer where the values will be stored. count The number of values to be read from the I/O port. DESCRIPTION
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. RETURN VALUES
The inb(), inw(), and inl() functions return the value that was read from the I/O port. CONTEXT
These functions may be called from user, interrupt, or kernel context. ATTRIBUTES
