💅 ACL_DELETE_ENTRY(3) 💅

okay bestie, this page is from the Library Functions Manual, and it’s all about deleting an ACL entry from an ACL. yes ma’am, the unlink-but-for-ACLs energy is real. 🎀

✨ NAME ✨

acl_delete_entry, acl_delete_entry_np — delete an ACL entry from an ACL. literally the whole point of this page, and she ate. 🫶

📚 LIBRARY 📚

Standard C Library (libc, -lc) — that’s the library, bestie. no cap. 💅

🧾 SYNOPSIS 🧾

#include <sys/types.h>
#include <sys/acl.h>

int
acl_delete_entry(acl_t acl, acl_entry_t entry_d);

int
acl_delete_entry_np(acl_t acl, int index);

💖 DESCRIPTION 💖

The acl_delete_entry() function is a POSIX.1e call that removes the ACL entry entry_d from ACL acl. periodt. 💖

The acl_delete_entry_np() function is a non-portable version that removes the ACL entry at position index from ACL acl. yes, she’s the _np icon, and she comes with a little “non-portable” warning label. 🦋

Positions are numbered starting from zero, i.e. calling acl_delete_entry_np() with the index argument equal to zero will remove the first ACL entry. so index 0 is giving “first entry, you are OUT.” 💀✨

🔁 RETURN VALUES 🔁

The acl_delete_entry() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

so: 0 = slay, -1 = check errno, bestie. 🫶

😭 ERRORS 😭

The acl_delete_entry() function fails if:

  • [EINVAL] — Argument acl does not point to a valid ACL. Argument entry_d is not a valid descriptor for an ACL entry in acl. Argument index is out of bounds.

yeah, all three of those live under [EINVAL], and none of them are cute. 🙈
