💖 MPI_T_PVAR_SESSION_FREE(3) — Open MPI bestie edition 💖

okay so bestie, welcome to the MPI_T_PVAR_SESSION_FREE(3) page from Open MPI. it’s literally the performance-variable session page, and the main characters are MPI_T_pvar_session_create and MPI_T_pvar_session_free. lowkey iconic, fr fr. 🫶

✨ NAME ✨

MPI_T_pvar_session_create, MPI_T_pvar_session_free - Create/free performance variable session

🛠️ SYNTAX 🛠️

🧚 C Syntax 🧚

#include <mpi.h>

int MPI_T_pvar_session_create(MPI_T_pvar_session *session)

int MPI_T_pvar_session_free(MPI_T_pvar_session *session)

💫 DESCRIPTION 💫

MPI_T_pvar_session_create creates a session for accessing performance variables. the new session is returned in the session parameter. slay, that’s the create vibe. ✨

MPI_T_pvar_session_free releases a session allocated by MPI_T_pvar_session_create and sets the session parameter to MPI_T_PVAR_SESSION_NULL. so it’s the cleanup bestie — very demure, very mindful. 🎀
