I/O Library (Windows Embedded CE 6.0)
1/5/2010
The I/O library implements I/O functions. It also contains functions used to map a bus address to a system address, read/write bus configuration space, and power off or power on bus controller. For more information, see %_WINCEROOT%\Platform\Common\Src\Inc\Oal_io.h.
Depending on your hardware platform, the I/O operations can be implemented as macros or as functions. By default, the code uses functions. If your hardware platform does not allow direct inline I/O operation, you must set the OAL_DDK_NOMACRO environment variable before the OAL libraries are compiled.
