ACL_FROM_MODE(3) Library Functions Manual ACL_FROM_MODE(3)
acl_from_mode — create an ACL from file permission bits
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <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 appropriately.
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).
