ceph_start_encoding(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ceph_start_encoding(9) β€” or, "how to open an encoding block, bestie"

okay so this is ceph_start_encoding, straight out of the Kernel API Manual (yes, the kernel has a manual, and yes it's iconic). Think of this function as the opening move β€” the "hey bestie, we're about to encode something" announcement ✨


🌸 NAME 🌸

ceph_start_encoding β€” start encoding block. that's it. that's the whole vibe. it kicks off an encoding block, periodt.


πŸŽ€ SYNOPSIS πŸŽ€

void ceph_start_encoding (void **p , u8 struct_v , u8 struct_compat ,
       u32 struct_len );

returns void, so like… no return value, no drama, it just does the thing 🫢


πŸ’– ARGUMENTS πŸ’–

  • p β€” literally listed as -- undescribed -- in the original, and ngl I'm not gonna invent lore for it. the docs said undescribed, so undescribed it stays 😭 it's a void **, make of that what you will πŸ™ˆ
  • struct_v β€” the current (code) version of the encoding. this is the version of the code doing the encoding, iykyk πŸ’…
  • struct_compat β€” the oldest code version that can decode it. so like, the bottom line of backwards compatibility β€” the oldest reader that still gets it πŸ‘‘
  • struct_len β€” length of struct encoding. the size. the amount. the u32 of it all ✨
