like, that's the whole vibe, that's the signature, no notes 💅

🎀 INPUT PARAMETERS 🎀

  • cat_index — the index of the category you're curious about, aka "which category are we snooping in bestie" 👀
  • len — the length of the indices array. yes, you gotta tell her how big your array is, she's not a mind reader 😭

✨ OUTPUT PARAMETERS ✨

  • indices — an integer array of size len, and it's giving "here are your control variable indices, you're welcome" 🎁

🔥 DESCRIPTION 🔥

so MPI_T_category_get_cvars is literally the function you call to query which control variables are contained in a particular category. that's it. that's the whole plot. no cap 💀

💀 ERRORS 💀

MPI_T_category_get_cvars will fail if:

  • MPI_T_ERR_NOT_INITIALIZED — the MPI Tools interface isn't initialized, like girl you gotta set things up first 🙈
  • MPI_T_ERR_INVALID_INDEX — the category index is invalid, meaning that index does not exist, bestie, it's a fake number 😭
