PetscDataType

 Used for handling different basic data types.

Synopsis

typedef enum {PETSC_INT = 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, PETSC_DATATYPE_UNKNOWN} 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?
