You mean like ubc_pages_resident()?
You probably want to look at the source code. The ubc code and its
KPI is very well documented by the block comments I placed in
ubc_subr.c. In fact much of xnu/bsd KPI has similar documentation
from my block comments.

Hi,
Is there a KPI to find out if a vnode currently has some cached
data in UBC?I basically need this information to keep my in core
inode cache, in sync with the vnodes.
Thanks,
