Solaris IA DDI specific (Solaris IA DDI).
|
| |
-
port
- A valid I/O port address.
-
value
- The data to be written to the I/O port.
-
addr
- The address of a buffer from which the values will be fetched.
-
count
- The number of values to be written to the I/O port.
|
| |
These routines write data of various sizes to the I/O port with the address specified by port.
The outb(), outw(), and outl() functions write 8 bits, 16 bits, and 32 bits of data respectively, writing the data specified by value.
The repoutsb(), repoutsw(), and repoutsd() functions write multiple 8-bit, 16-bit, and 32-bit values, respectively. count
specifies the number of values to be written. addr is a pointer to a buffer from which the output values are fetched.
|
| |
These functions may be called from user or interrupt context.
