📦 version 7.3.1, in nixpkgs unstable

🎀 assoc_array_delete(9) 🎀

okay so bestie, this one lives in the Kernel API Manual and it's literally called assoc_array_delete — yes, she's a kernel function, yes she's iconic 💅

✨ NAME ✨

assoc_array_delete — script the deletion of an object from an associative array 🗑️✨

🌸 SYNOPSIS 🌸

struct assoc_array_edit * assoc_array_delete (struct assoc_array *array
, const struct assoc_array_ops *ops , const void *index_key );

like, look at her go 😭 so many parameters but she's serving 🫶

💖 ARGUMENTS 💖

  • array — the array you're searching, bestie. that's the one. 🔍
  • ops — the operations to use. the whole vibe of how she works 🛠️
  • index_key — the key to the object. iykyk 🔑

🦋 DESCRIPTION 🦋

so the whole point: this function precalculates and preallocates a script for the deletion of an object from an associative array. no cap. it hands you back an edit script that you can either apply or cancel — your call, main character 🌈

the function returns a pointer to an edit script if the object was found, NULL if the object was not found or -ENOMEM 💀 (yes, that's a thing it returns, we don't ask questions)

⚠️ okay so real talk: the caller should lock against other modifications, and must continue to hold the lock until assoc_array_apply_edit has been called. do not let go early. periodt 🔒

accesses to the tree may totally take place concurrently with this function, provided they hold the RCU read lock 🧚✨
