#define RTAPI_INT__xx___MAX ...
#define RTAPI_UINT__xx___MAX ...DESCRIPTION
In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available.
In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation—possibly with reduced functionality—is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)
REALTIME CONSIDERATIONS
None.
RETURN VALUE
As in Linux.
