NAME¶
MPI_T_pvar_handle_alloc, MPI_T_pvar_handle_free - Allocate/free
MPI performance variable handles
C Syntax¶
#include <mpi.h>
int MPI_T_pvar_handle_alloc(int pvar_index, void *obj_handle,
MPI_T_pvar_handle *handle, int *count)
int MPI_T_pvar_handle_free(MPI_T_pvar_handle *handle)
DESCRIPTION¶
MPI_T_pvar_handle_alloc binds the performance variable specified in
pvar_index to the MPI object specified in obj_handle. If
MPI_T_pvar_get_info returns MPI_T_BIND_NO_OBJECT as the binding for the
variable the obj_handle argument is ignored. The number of values
represented by this performance variable is returned in the count
parameter.
MPI_T_pvar_handle_free frees a handle allocated by
MPI_T_pvar_handle_alloc and sets the handle argument to
MPI_T_PVAR_HANDLE_NULL.
ERRORS¶
MPI_T_pvar_handle_alloc() will fail if:
- [MPI_T_ERR_NOT_INITIALIZED]
- The MPI Tools interface not initialized
- [MPI_T_ERR_INVALID_INDEX]
- The performance variable index is invalid
- [MPI_T_ERR_OUT_OF_HANDLES]
- No more handles available
- MPI_T_pvar_handle_free() will fail if:
- [MPI_T_ERR_NOT_INITIALIZED]
- The MPI Tools interface not initialized
- [MPI_T_ERR_INVALID_HANDLE]
- The handle is invalid
