🌸 NAME 🌸

tpm2tss_tpm2data_write, tpm2tss_tpm2data_read – read/write TPM2_DATA

like. it reads. it writes. it's giving duality. 🦋

---

🎀 SYNOPSIS 🎀

#include <tpm2tss.h>

**int tpm2tss_tpm2data_read(const char *filename, TPM2_DATA tpm2Datap);

int tpm2tss_tpm2data_write(const TPM2_DATA tpm2Data, const char filename);

bestie the ** in that first line is literally how the manpage prints it, so I'm keeping it exactly as-is. do not come for me. 🙈

✨ DESCRIPTION ✨

🍓 tpm2tss_tpm2data_read

so tpm2tss_tpm2data_read reads the TPM2_DATA object out of a file called filename, allocates memory, and stores it under the parameter tpm2Datap.

and here's the part you CANNOT skip, iykyk: that memory must be freed using the free() function. bestie. free your memory. it's not a vibe to leak. 💀

🧚 tpm2tss_tpm2data_write

meanwhile tpm2tss_tpm2data_write takes the TPM2_DATA object from the parameter tpm2Data and writes it to a newly created file called filename.

newly created. like it's making a whole new file, iconic behavior honestly. 👑

---

⭐ RETURN VALUE ⭐

upon successful completion, tpm2tss_tpm2data_write() and tpm2tss_tpm2data_read() return 1.

otherwise 0.

that's it. that's the whole vibe check. 1 = slay, 0 = not slay. 💅
