acl_from_mode: create an ACL from file permission bits
acl_from_mode - create an ACL from file permission bits
LIBRARYLinux Access Control Lists library (libacl, -lacl).
SYNOPSISIn sys/types.h In acl/libacl.h Ft acl_t Fn acl_from_mode mode_t mode
DESCRIPTIONThe Fn 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 VALUEOn 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.
ERRORSIf any of the following conditions occur, the Fn acl_from_mode function returns a value of (acl_t)NULL and sets errno to the corresponding value:
- Bq Er ENOMEM
- The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDSThis is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned).
