MPI_T_category_get_cvars(3) MPI MPI_T_category_get_cvars(3)
NAME
MPI_T_category_get_cvars - Get control variables in a category
SYNOPSIS
int MPI_T_category_get_cvars(int cat_index, int len, int indices[])
INPUT PARAMETERS
cat_index
- index of the category to be queried, in the range $0$ and
$num_cat-1$ (integer)
len - the length of the indices array (integer)
OUTPUT PARAMETERS
indices
- an integer array of size len, indicating control variable
indices (integer)
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_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.
