NAME
       acl_valid - Checks an ACL for validity

LIBRARY
       Security Library (libpacl.a)

SYNOPSIS
       #include <sys/acl.h>
       int acl_valid(	   acl_t acl_d,      acl_entry_t *entry_p);

PARAMETERS
       Specifies the working storage internal representation of an ACL.  Pointer to the location that holds a returned ACL entry.

DESCRIPTION
       NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard.

       The acl_valid() function checks the ACL for validity.  An ACL is invalid if one or more of the following conditions are violated: The three
       required entries (ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER_OBJ) must appear exactly once in an ACL of type ACL_TYPE_ACCESS, and in a non-
       empty ACL of type ACL_TYPE_DEFAULT or ACL_TYPE_DEFAULT_DIR.  The ACL must not contain a duplicate entry.  An entry is duplicated if another
       entry in the same ACL has the same entry tag type and the same tag qualifier (sameness or difference in permissions is not relevant).

RETURN VALUES
       Upon successful completion, the acl_valid() function returns a value of 0 (zero).  Otherwise, a value of -1  is	returned,  and	the  errno
       global variable is set to indicate the error.

ERRORS
       For  the following condition, the acl_valid() function sets the location specified by the entry_p parameter with the value of the ACL entry
       for which one or more duplicates exist elsewhere in the ACL.  The ACL contains entries that are not unique.

       For the following conditions, the acl_valid() function sets the location indicated by the entry_p parameter to the NULL value.	The  acl_d
       parameter does not refer to a valid ACL.

       One or more of the required entries is not present.
