[petsc-users] PetscSFReduceBegin can not handle MPI_CHAR?

[Fande Kong]

Hi All,

There were some error messages when using PetscSFReduceBegin with MPI_CHAR.

ierr =
PetscSFReduceBegin(ptap->sf,MPI_CHAR,rmtspace,space,MPI_SUM);CHKERRQ(ierr);


My question would be: Does PetscSFReduceBegin suppose work with MPI_CHAR?
If not, should we document somewhere?

Thanks

Fande,
