The n is the IXPCI device number.

ioctl Commands

IXPCI_GET_INFO
Retrieve a device's information, and put it into the ixpci_devinfo (ixpci_devinfo_t) structure. Example: list.c.
IXPCI_READ_REG
Read a specified register's value, and put the value into the ixpci_reg (ixpci_reg_t) structure. Example: ixpcitmc12/dio.c
IXPCI_WRITE_REG
Write a given value to a specified register. Example: ixpcitmc12/dio.c
IXPCI_SET_SIG
Set interrupt signaling condition. Example: pcitmc12/int.c
IXPCI_IOCTL_DI
Digital input. Example: pcitmc12/dio2.c
IXPCI_IOCTL_DO
Digital output. Example: pcitmc12/dio2.c
IXPCI_RESET
Reset device.Example: ixpcitmc12/rst.c

Data Structures

ixpci_devinfo_t
The data type of structure ixpci_devinfo which contains a device's id, base address, and so on. Example: list.c
