acl_valid(3)
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
  acl_d	    Specifies the working storage internal representation of an ACL.

  entry_p   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 function may change as the P1003.6 standard is finalized.

  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 ACCESS type, and
       in a nonempty ACL of DEFAULT type.

    ·  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.

  [EINVAL]		   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.

  [EINVAL]	 The acl_d parameter does not refer to a valid ACL.

		 One or more of the required entries is not present.


  [ENONEM]	 Too many entries (greater than MAX_IR_ENTRIES)
