NAME

       MPI_Errhandler_create -  Creates an MPI-style errorhandler

SYNOPSIS

       int MPI_Errhandler_create(MPI_Handler_function * function, MPI_Errhandler * errhandler)

INPUT PARAMETERS

       function
              - user defined error handling procedure

OUTPUT PARAMETERS

       errhandler
              - MPI error handler (handle)

NOTES

       The  MPI Standard states that an implementation may make the output value (errhandler) simply the address
       of the function.  However, the action of MPI_Errhandler_free makes this impossible, since it is  required
       to  set  the  value  of the argument to MPI_ERRHANDLER_NULL .  In addition, the actual error handler must
       remain until all communicators that use it are freed.

THREAD AND INTERRUPT SAFETY

       This routine is thread-safe.  This means that this routine may be safely used by multiple threads without
       the need for any user-provided thread locks.  However, the routine is  not  interrupt  safe.   Typically,
       this  is  due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines
       that are themselves not interrupt-safe.

DEPRECATED FUNCTION

       The MPI-2 standard deprecated a number of routines because MPI-2 provides better versions.  This  routine
       is  one  of  those that was deprecated.  The routine may continue to be used, but new code should use the
       replacement routine.  The replacement routine for this function is MPI_Comm_create_errhandler .

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the
       end of the argument list.  ierr is an integer and has the same meaning as the return value of the routine
       in C.  In Fortran, MPI routines are subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of  the
       function  and Fortran routines in the last argument.  Before the value is returned, the current MPI error
       handler is called.  By default, this error handler aborts the MPI job.  The error handler may be  changed
       with    MPI_Comm_set_errhandler   (for   communicators),   MPI_File_set_errhandler   (for   files),   and
       MPI_Win_set_errhandler (for RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but  its  use
       is  deprecated.   The  predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be
       returned.  Note that MPI does not guarentee that an MPI program can continue past an error; however,  MPI
       implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_INTERN
              - This error is returned when some part of the MPICH implementation is unable to acquire memory.
