NAME
MPIR_Type_indexed - create an indexed datatype
SYNOPSIS
int MPIR_Type_indexed(int count,
const int *blocklength_array,
const void *displacement_array,
int dispinbytes, MPI_Datatype oldtype, MPI_Datatype * newtype)
INPUT PARAMETERS
- count
-
- number of blocks in type
- blocklength_array
-
- number of elements in each block
- displacement_array
-
- offsets of blocks from start of type (see next parameter for units)
- dispinbytes
-
- if nonzero, then displacements are in bytes (the displacement_array is an array of ints), otherwise they in terms of extent of oldtype (the displacement_array is an array of MPI_Aints)
- oldtype
-
- type (using handle) of datatype on which new type is based
OUTPUT PARAMETERS
- newtype
-
- handle of new indexed datatype
RETURN VALUE
0 on success, -1 on failure.
