const int *blocklength_array,

const void *displacement_array,

int dispinbytes, MPI_Datatype oldtype, MPI_Datatype * newtype)

.fi

.SH INPUT PARAMETERS

.PD 0

.TP

.B count 

- number of blocks in type

.PD 1

.PD 0

.TP

.B blocklength_array 

- number of elements in each block

.PD 1

.PD 0

.TP

.B displacement_array 

- offsets of blocks from start of type (see next

parameter for units)

.PD 1

.PD 0

.TP

.B 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)

.PD 1

.PD 0

.TP

.B oldtype 

- type (using handle) of datatype on which new type is based

.PD 1

.SH OUTPUT PARAMETERS

.PD 0

.TP

.B newtype 

- handle of new indexed datatype

.PD 1

.SH RETURN VALUE

0 on success, -1 on failure.
