kvm_getfiles(kvm_t *kd, int op, int arg, int *cnt);
The kvm_getfiles() function returns a (sub-)set of the open files in the
kernel indicated by kd. The op and arg arguments constitute a predicate
which limits the set of files returned. No predicates are currently
defined.
The number of files found is returned in the reference parameter cnt.
The files are returned as a contiguous array of file structures, preceded
by the address of the first file entry in the kernel. This memory is
owned by kvm and is not guaranteed to be persistent across subsequent kvm
library calls. Data should be copied out if it needs to be saved.
The kvm_getfiles() function will return NULL on failure.
This routine does not belong in the kvm interface.
