getptyp(point_type_name,point_type,ierror)

This routine converts point type names to point types.
See III.a for a list of point types, names and meanings
point_type_name            name of point type (character*32)
point_type                       value of point type (integer)

unpackpc(npoints,itp,isn,iparents)

This routine returns in the array iparents the parent point corresponding to each child point i, if point i is a child point. Ordinary points are their own parents.  The first three arguments are usually mesh object attributes described in Section III.a
npoints                        input number of nodes (integer)
itp1                             input array of point types (integer array)
isn1                             input array of parent child links (integer array)
iparents                       input/output array of parent node number for each point (integer array)

unpacktp(ioptitp,iopt2,inum,ipitp1,ipitp2,ierror) This routine sets, or's in, or and's in (depending on iopt2) a 1 in the array pointed to by ipitp2 for each point that fits the criterion specified by ioptitp. ioptitp uses the point types as defined in Section III.a   and ipitp1is the pointer to the integer array of point types.
A zero is set, or'd or and'd otherwise.
