[petsc-users] VecGetOwnershipRanges

[Hui Zhang]

VecGetOwnershipRanges(Vec x,const PetscInt *ranges[])

From the html manual page,

range -array of length size+1 with the start and end+1 for each process 

Is it PetscInt ranges[size+1][2] or PetscInt ranges[size+1]?

The function calls

PetscLayoutGetRanges(PetscLayout map,const PetscInt *range[])

for which the manual page says

range -start of each processors range of indices (the final entry is one more then the last index on the last process) 

I'm sorry that I'm confused.
