ACL_FROM_MODE(3) BSD Library Functions Manual ACL_FROM_MODE(3)
acl_from_mode — create an ACL from file permission bits
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <acl/libacl.h>
acl_t
acl_from_mode(mode_t mode);
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.
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 appropri‐
ately.
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:
[ENOMEM] The ACL working storage requires more memory than is
allowed by the hardware or system-imposed memory
management constraints.
This is a non-portable, Linux specific extension to the ACL
manipulation functions defined in IEEE Std 1003.1e draft 17
(“POSIX.1e”, abandoned).
