NAME
acl_from_mode —
create an ACL from file permission bits
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include
<sys/types.h>
#include <acl/libacl.h>
acl_t
acl_from_mode(mode_t
mode);
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:
- [
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).
