NAME

MPI_Type_size - Returns the size of a type in bytes

SYNOPSIS

#include <mpi.h> 
int MPI_Type_size(MPI_Datatype datatype , int *size ); 
#include <pmpi.h> 
int PMPI_Type_size(MPI_Datatype datatype , int *size ); 

INPUT PARAMETER

datatype - type (handle)

OUTPUT PARAMETER

size - size of that type in bytes (integer).

DESCRIPTION

The MPI_Type_size() function is used to determine the size of a type in bytes. This is the total room taken by all the subtypes. Note that some types have zero size, such as MPI_UB.

PMPI_Type_size() is the profiling version of this function.

ERRORS

All MPI routines except for MPI_Wtime and MPI_Wtick return an error value. The the current MPI error handler is invoked if this return value is not MPI_SUCCESS. The default error handler aborts, but this may be changed with by using the MPI_Errhandler_set() function. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned instead. Note that MPI does not guarentee that an MPI program can continue past an error. In this implementation, all errors except MPI_ERR_INTERN or MPI_ERR_OTHER should always be recoverable.

MPI_SUCCESS - No error;

MPI_ERR_TYPE - Invalid data type;

MPI_ERR_ARG - Invalid pointer.
