Indices in IPIV array for LU related functions

All LU (and also QR with column pivoting) related LAPACK functions has as an argument an array IPIV that stores the indices of row (columns for QR) permutations. In the C interface of CULA, are the indices of this array 0-based or 1-based, as in Fortran?, i.e., an index for the first row , is stored as 0 or as 1?
