MPI_T_pvar_handle_alloc(3) MPI MPI_T_pvar_handle_alloc(3)

MPI_T_pvar_handle_alloc - Allocate a handle for a performance variable

int MPI_T_pvar_handle_alloc(MPI_T_pvar_session session, int pvar_index,
void *obj_handle, MPI_T_pvar_handle * handle, int *count)

session
- identifier of performance experiment session (handle)
pvar_index
- index of performance variable for which handle is to be allocated (integer)
obj_handle
- reference to a handle of the MPI object to which this variable is supposed to be bound (pointer)

handle
- allocated handle (handle)
count
- number of elements used to represent this variable (integer)

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.

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_NOT_INITIALIZED
- The MPI tool information interface is not initialized.
MPI_T_ERR_INVALID_SESSION
- Session argument is not valid.
MPI_T_ERR_INVALID_INDEX
- Index is invalid or has been deleted.
MPI_T_ERR_OUT_OF_HANDLES
- No more handles available.
