MPI_T_category_get_pvars — Query which performance variables are in a category

#include <mpi.h>
int MPI_T_category_get_pvars(int cat_index, int len, int indices[])


  • cat_index: Index of the category to be queried.
  • len: The length of the indices array.

•
indices: An integer array of size len, indicating performance variable indices.

MPI_T_category_get_pvars can be used to query which performance variables are contained in a particular category. A category contains zero or more performance variables.

MPI_T_category_get_pvars will fail if:

  • MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized
  • MPI_T_ERR_INVALID_INDEX: The category index is invalid
