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_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. 2/3/2025 MPI_T_event_callback_set_info(3)
