     acl_create_entry — create a new ACL entry


     Linux Access Control Lists library (libacl, -lacl).


     #include <sys/types.h>
     #include <sys/acl.h>

     acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);


     The acl_create_entry() function creates a new ACL entry in the ACL pointed to by the
     contents of the pointer argument acl_p.  On success, the function returns a descriptor for
     the new ACL entry via entry_p.

     This function may cause memory to be allocated.  The caller should free any releasable
     memory, when the new ACL is no longer required, by calling acl_free(3) with (void*)*acl_p as
     an argument.  If the ACL working storage cannot be increased in the current location, then
     the working storage for the ACL pointed to by acl_p may be relocated and the previous
     working storage is released. A pointer to the new working storage is returned via acl_p.

     The components of the new ACL entry are initialized in the following ways: the ACL tag type
     component contains ACL_UNDEFINED_TAG, the qualifier component contains ACL_UNDEFINED_ID, and
     the set of permissions has no permissions enabled. Any existing ACL entry descriptors that
     refer to entries in the ACL continue to refer to those entries.


     The acl_create_entry() function returns the value 0 if successful; otherwise the value -1 is
     returned and the global variable errno is set to indicate the error.


     If any of the following conditions occur, the acl_create_entry() function returns -1 and
     sets errno to the corresponding value:

     [EINVAL]           The argument acl_p is not a valid pointer to an ACL.

     [ENOMEM]           The ACL working storage requires more memory than is allowed by the
                        hardware or system-imposed memory management constraints.
