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_pci_register always succeeds)

REALTIME CONSIDERATIONS

Typically, these functions may be called from realtime init/cleanup code.

RETURN VALUE

As in Linux.
