NAME         top

LIBRARY         top

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

SYNOPSIS         top

       <sys/types.h> <sys/acl.h> int acl_set_permset(acl_entry_t
       entry_d, acl_permset_t permset_d)

DESCRIPTION         top

       The acl_set_permset() function sets the permission set of the ACL
       entry indicated by the argument entry_d to the permissions
       contained in the argument permset_d.

       Any ACL entry descriptors that refer to the entry containing the
       permission set referred to by permset_d shall continue to refer
       to those entries. Any ACL entry descriptors that refer to the
       entry referred to by entry_d shall continue to refer to that

RETURN VALUE         top

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

ERRORS         top

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

       [EINVAL]           The argument entry_d is not a valid descriptor
                          for an ACL entry.

                          The argument permset_d is not a valid
                          descriptor for a permission set within an ACL

                          The argument permset_d contains values which
                          are not valid acl_permset_t values.
