MPI_Type_create_struct function - Message Passing Interface (original) (raw)

Defines a new data type with a specified data type, displacement, and size for each block of data.

Syntax

int MPIAPI MPI_Type_create_struct(
        int                            count,
        _In_count_(count) int          array_of_blocklengths[],
        _In_count_(count) MPI_Aint     array_of_displacements[],
        _In_count_(count) MPI_Datatype array_of_types[],
  _Out_ MPI_Datatype                   *newtype
);

Parameters

count
The number of blocks and the number of entries in the array_of_blocklengths, array_of_displacements and array_of_types parameters.
array_of_blocklengths
The number of elements of each block.
array_of_displacements
The displacement of each individual block in bytes.
array_of_types
The data type of each individual block.
newtype [out]
On return, contains an MPI_Datatype handle that represents the new data type.

Return value

Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.

In Fortran, the return value is stored in the IERROR parameter.

Fortran

    MPI_TYPE_CREATE_STRUCT(COUNT, ARRAY_OF_BLOCKLENGTHS, ARRAY_OF_DISPLACEMENTS, ARRAY_OF_TYPES, NEWTYPE, IERROR)
        COUNT, ARRAY_OF_BLOCKLENGTHS, ARRAY_OF_DISPLACEMENTS, ARRAY_OF_TYPES, NEWTYPE, IERROR

This function replaces the MPI_Type_struct function, which is deprecated.
