.SH 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)
|
|
.SH REALTIME CONSIDERATIONS
|
|
Typically, these functions may be called from realtime init/cleanup code.
|
|
.SH RETURN VALUE
|
|
As in Linux.
