man acl_from_mode (Fonctions bibliothèques) - acl_from_mode
NAME
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
DESCRIPTION
The acl_from_mode function creates a minimal ACL that contains the three entries with tag types ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER, with permissions corresponding to the owner, group, and other permission bits of its argument mode .
RETURN VALUE
On success, this function returns a pointer to the working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.
ERRORS
If any of the following conditions occur, the acl_from_mode function returns a value of (acl_t)NULL and sets errno to the corresponding value:
- Bq ENOMEM
- The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 (POSIX.1e, abandoned).
