! File: psi_idx_ins_cnv.f90
!
! Subroutine: psi_idx_ins_cnv1
! Converts a bunch of indices from global to local numbering.
! This routine is called while the descriptor is in the build state;
! the idea is that if an index is not yet marked as local, it is a new
! connection to another process, i.e. a new entry into the halo.
! But we still need the mask, because we have to take out the column indices
! corresponding to row indices we do not own (see psb_cdins for how this is used).
!
! Arguments:
! nv - integer Number of indices required
! idxin(:) - integer Required indices, overwritten on output
! output is negative for masked entries
! desc - type(psb_desc_type). The communication descriptor.
! info - integer. return code.
! mask(:) - logical, optional Only do the conversion for specific indices.
