cipso_v4_gentag_rng(9)

✨ NAME ✨

okay so this is cipso_v4_gentag_rng(9) from the Kernel API Manual, and she is literally the range-tag generator bestie 💅

• cipso_v4_gentag_rng - Generate a CIPSO ranged tag (type #5)

🌸 SYNOPSIS 🌸

       int cipso_v4_gentag_rng (const struct cipso_v4_doi *doi_def , const
       struct netlbl_lsm_secattr *secattr , unsigned char *buffer , u32
       buffer_len );

🎀 ARGUMENTS 🎀

• doi_def — the DOI definition, no cap.
• secattr — the security attributes, iconic.
• buffer — the option buffer, the little stage where the magic goes.
• buffer_len — length of buffer in bytes, periodt.

💅 DESCRIPTION 💅

Generate a CIPSO option using the ranged tag, tag type #5. Returns the size of the tag on success, negative values on failure.

so yeah bestie: on success she hands you back the size of the tag, and on failure it’s negative values 😭 that’s the whole vibe.
