PetscDataType

Used for handling different basic data types.

Synopsis

typedef enum {PETSC_DATATYPE_UNKNOWN = 0,
              PETSC_DOUBLE = 1, PETSC_COMPLEX = 2, PETSC_LONG = 3, PETSC_SHORT = 4, PETSC_FLOAT = 5,
              PETSC_CHAR = 6, PETSC_BIT_LOGICAL = 7, PETSC_ENUM = 8, PETSC_BOOL = 9, PETSC___FLOAT128 = 10,
              PETSC_OBJECT = 11, PETSC_FUNCTION = 12, PETSC_STRING = 13, PETSC___FP16 = 14, PETSC_STRUCT = 15,
              PETSC_INT = 16, PETSC_INT64 = 17} PetscDataType;

Notes

Use of this should be avoided if one can directly use MPI_Datatype instead.

Developer comment

It would be nice if we could always just use MPI Datatypes, why can we not?
