ocs_hcu_hash_final(9)

🌸 NAME 🌸

ocs_hcu_hash_final — finalize hash computation, bestie. This is the ocs_hcu_hash_final(9) page in the Kernel API Manual, and yes, it’s giving “last step” energy ✨.

✨ SYNOPSIS ✨

int ocs_hcu_hash_final (struct ocs_hcu_dev *hcu_dev , const struct
ocs_hcu_hash_ctx *ctx , u8 *dgst , size_t dgst_len );

🎀 ARGUMENTS 🎀

• hcu_dev — the OCS HCU device to use, bestie.
• ctx — the OCS HCU hashing context.
• dgst — the buffer where the computed digest gets saved. That’s where the final digest goes, periodt.
• dgst_len — the length of dgst.

💖 RETURN 💖

0 on success; a negative error code otherwise. So like, success is 0, and bad vibes are a negative error code, fr fr.
