NAME

       MPI_T_source_get_info  -   Returns  additional information on the source identified by the
       source_index argument

SYNOPSIS

       int MPI_T_source_get_info(int source_index, char *name, int *name_len,
       char *desc, int *desc_len,
       MPI_T_source_order *ordering,
       MPI_Count *ticks_per_second, MPI_Count *max_ticks,
       MPI_Info *info)

INPUT PARAMETERS

       source_index
              - index of the source to be queried between $0$ and $num_sources-1$ (integer)

INPUT/OUTPUT PARAMETERS

       name_len
              - length of the string and/or buffer for name (integer)
       desc_len
              - length of the string and/or buffer for desc (integer)

OUTPUT PARAMETERS

       name   - buffer to return the string containing the name of the source (string)
       desc   - buffer to return the string containing the description of the source (string)
       ordering
              - flag indicating chronological ordering guarantees given by the source (integer)
       ticks_per_second
              - the number of ticks per second for the timer of this source (integer)
       max_ticks
              - the maximum count of  ticks  reported  by  this  source  before  overflow  occurs
              (integer)
       info   - info argument (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
       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  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_T_ERR_INVALID
              - Invalid use of the interface or bad parameter values(s).
       MPI_T_ERR_INVALID_INDEX
              - Index is invalid or has been deleted.
       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.
