NAME

       MPI_Sizeof - Returns the size, in bytes, of the given type

SYNTAX

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_SIZEOF(X, SIZE, IERROR)
       <type>    X
       INTEGER   SIZE, IERROR

INPUT PARAMETER

       X         A Fortran variable of numeric intrinsic type (choice).

OUTPUT PARAMETERS

       SIZE      Size of machine representation of that type (integer).

       IERROR    Error status (integer).

DESCRIPTION

       MPI_SIZEOF  returns  the  size  (in  bytes)  of  the  machine  representation of the given
       variable. It is a generic Fortran type and has a Fortran binding  only.  This  routine  is
       similar  to  the  sizeof builtin in C/C++. However, if given an array argument, it returns
       the size of the base element, not the size of the whole array.

NOTES

       This function is not available in C/C++ because it is not necessary.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran  routines in the last argument. C++ functions do not return errors. If the default
       error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then  on  error  the  C++  exception
       mechanism will be used to throw an MPI::Exception object.

       Before  the  error value is returned, the current MPI error handler is called. By default,
       this error handler aborts the MPI job, except for I/O function errors. The  error  handler
       may    be   changed   with   MPI_Comm_set_errhandler;   the   predefined   error   handler
       MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not
       guarantee that an MPI program can continue past an error.

       See the MPI man page for a full list of MPI error codes.
