MPI_Sizeof(3)                      Open MPI                      MPI_Sizeof(3)



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 intrisic 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.
