MPI_T_event_callback_set_info(3) MPI MPI_T_event_callback_set_info(3)
NAME
MPI_T_event_callback_set_info - Updates the hints of the callback
function registered for the callback safety level specified by
cb_safety of the event-registration handle associated with event_regis-
tration
SYNOPSIS
int MPI_T_event_callback_set_info(MPI_T_event_registration event_registration,
MPI_T_cb_safety cb_safety, MPI_Info info)
INPUT PARAMETERS
event_registration
- event registration (handle)
cb_safety
- callback safety level (integer)
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_errhandler (for RMA windows). The MPI-1 routine
MPI_Errhandler_set may be used but its use is deprecated. The prede-
fined 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 whenever 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.
