ACL_FROM_MODE(3) BSD Library Functions Manual ACL_FROM_MODE(3)

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 appropri- ately.

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 man- agement 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).
