MPI_T_event_handle_set_info(3)	      MPI	MPI_T_event_handle_set_info(3)

NAME
       MPI_T_event_handle_set_info -  Updates the hints	of the event-registra-
       tion handle associated with event_registration

SYNOPSIS
       int MPI_T_event_handle_set_info(MPI_T_event_registration	event_registration,
       MPI_Info	info)

INPUT PARAMETERS
       event_registration
	      -	event registration (handle)
       info   -	info object (handle)

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.

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 com-
       municators),  MPI_File_set_errhandler  (for files), and MPI_Win_set_er-
       rhandler	(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 guarantee that an MPI program can continue past
       an error; however, MPI implementations will attempt to  continue	 when-
       ever possible.

       MPI_SUCCESS
	      -	No error; MPI routine completed	successfully.
       MPI_ERR_INFO
	      -	Invalid	Info
       MPI_T_ERR_INVALID_HANDLE
	      -	The handle is invalid.
       MPI_T_ERR_NOT_INITIALIZED
	      -	The MPI	tool information interface is not initialized.
       MPI_ERR_OTHER
	      -	 Other	error;	use  MPI_Error_string  to get more information
	      about this error code.
