The pid2proc and vnode2path functions are part of the ON-private mdb kernel
support module. They're not part of the public API, but you could either
copy their declarations, or grab the "mdb_ks.h" file from
usr/src/cmd/mdb/common/mdb/mdb_ks.h
in the opensolaris source into the same directory as your source file, and
include it using #include "mdb_ks.h".
