Can someone help me to review this routine?

MatCreate_MPIAdj(Mat B)

I understand that MATMPIADJ is rather special, but the call above is never made


then It seems that some stuff (ranges) in the column map will be uninitialized.

What values should have the entries in "cmap" for mpiadj matrices?
Should the "comm" in "cmap" be MPI_COMM_SELF, then we can call
