MPI_Type_create_struct - Create an MPI datatype from a general set of
datatypes, displacements, and block sizes
Input Parameters:
+ count - number of blocks (integer) --- also number of entries in arrays
array_of_types, array_of_displacements and array_of_blocklengths
. array_of_blocklengths - number of elements in each block (array of integer)
. array_of_displacements - byte displacement of each block (array of address integer)
- array_of_types - type of elements in each block (array of handles to
datatype objects)
Output Parameters:
. newtype - new datatype (handle)
.N ThreadSafe
.N Fortran
.N Errors
.N MPI_SUCCESS
.N MPI_ERR_ARG
.N MPI_ERR_TYPE
