MPI_Initialized(3OpenMPI)												 MPI_Initialized(3OpenMPI)

NAME

       MPI_Initialized - Indicates whether MPI_Init has been called.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Initialized(int *flag)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_INITIALIZED(FLAG, IERROR)
	    LOGICAL   FLAG
	    INTEGER   IERROR

C++ Syntax
       #include <mpi.h>
       bool Is_initialized()

OUTPUT PARAMETERS

       flag	 Flag is true if MPI_Init has been called and false otherwise.

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       This  routine  may  be  used  to  determine  whether MPI_Init has been called. It is the only routine that may be called before MPI_Init is
       called.

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++ func-
       tions  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.
