MPI_T_enum_get_item

Synopsis

int MPI_T_enum_get_item(MPI_T_enum enumtype, int indx, int *value, char *name,
                        int *name_len)

Input Parameters

enumtype

enumeration to be queried (handle)

indx

number of the value to be queried in this enumeration (integer)

Input/Output Parameters

name_len

length of the string and/or buffer for name (integer)

Output Parameters

value

variable value (integer)

name

buffer to return the string containing the name of the enumeration item (string)

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_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.
