Tss2_TctiLdr_FreeInfo(3)

💖 Tss2_TctiLdr_FreeInfo(3) 💖

okay bestie so this is a page from the Library Functions Manual, and today's main character is Tss2_TctiLdr_FreeInfo — yes she's a cleanup girlie and honestly? we stan a function that knows how to let go. 🫶

---

✨ NAME ✨

Tss2_TctiLdr_FreeInfo — the function that frees a TSS2_TCTI_INFO structure that got allocated by Tss2_TctiLdr_Initialize(). 🧚

---

🌸 SYNOPSIS 🌸

#include <tss2/tss2_tctildr.h>

void Tss2_TctiLdr_FreeInfo (TSS2_TCTI_INFO*info);

---

💅 DESCRIPTION 💅

so basically, Tss2_TctiLdr_FreeInfo() destroys an instance of the TSS2_TCTI_INFO structure that was created by the Tss2_TctiLdr_GetInfo() function. it's giving ✨closure✨, it's giving release the memory back to the universe, no cap.

the info parameter is a reference to the TSS2_TCTI_INFO structure that's about to be freed. that's it. that's the whole job. iconic behaviour honestly. 👑

---

🌈 RETURN VALUE 🌈

this function returns no value. literally nothing. void core. she does her thing and leaves, no notes, no receipt, no drama. 💀

---

⭐ EXAMPLE ⭐

Example code. (yes bestie, real code, go look 👀)

#include <inttypes.h>
#include <stdlib.h>
#include <stdio.h>

#include <tss2/tss2_tctildr.h>

TSS2_TCTI_INFO *info = NULL;
TSS2_RC rc = Tss2_TctiLdr_GetInfo (NULL, &info);
if (rc != TSS2_RC_SUCCESS) {
    fprintf (stderr, "Failed to get TSS2_TCTI_INFO structure for default "
             "TCTI with response code: 0x%" PRIx32 "0, rc);
    exit (EXIT_FAILURE);
}

if (info != NULL) {
    Tss2_TctiLdr_FreeInfo (info);
    info = NULL;
}

exit (EXIT_SUCCESS);

quick vibe check bestie: see how she checks info != NULL before freeing, and then sets info = NULL right after? that's the self-care. that's the "we don't leave dangling pointers in this house" energy. 🔥
