ACL_TO_ANY_TEXT(3)	 BSD Library Functions Manual	    ACL_TO_ANY_TEXT(3)

     acl_to_any_text — convert an ACL to text

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

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

     char *
     acl_to_any_text(acl_t acl, const char *prefix, char separator,
	 int options);

     The acl_to_any_text() function translates the ACL pointed to by the argu‐
     ment acl into a NULL terminated character string. This character string
     is composed of the ACL entries contained in acl, in the entry text format
     described on acl(5).  Entries are separated from each other by the
     separator character. If the argument prefix is not (const char *)NULL,
     each entry is prefixed by this character string.

     If the argument options is 0, ACL entries are converted using the entry
     tag type keywords user, group, mask, and other.  User IDs and group IDs
     of ACL entries that contain such qualifiers are converted to their corre‐
     sponding names; if an identifier has no corresponding name, a decimal
     number string is produced. The ACL text representation contains no addi‐
     tional comments.  A bitwise combinations of the following options can be
     used to modify the result:

		   Instead of the full tag type keywords, single letter abbre‐
		   viations are used.  The abbreviation for user is u, the
		   abbreviation for group is g, the abbreviation for mask is
		   m, and the abbreviation for other is o.

		   User IDs and group IDs are included as decimal numbers
		   instead of names.

		   A comment containing the effective permissions of the ACL
		   entry is included after ACL entries that contain permis‐
		   sions which are ineffective because they are masked by an
		   ACL_MASK entry. The ACL entry and the comment are separated
		   by a tab character.

		   A comment containing the effective permissions of the ACL
		   entry is included after all ACL entries that are affected
		   by an ACL_MASK entry.  The comment is included even if the
		   permissions contained in the ACL entry equal the effective
		   permissions. The ACL entry and the comment are separated by
		   a tab character.

		   This option is used in combination with the
		   ber of tab characters inserted between the ACL entry and
		   the comment is increased so that the comment is aligned to
		   the fourth tab stop position.  A tab width of 8 characters
		   is assumed.

     The ACL referred to by acl is not changed.

     This function allocates any memory necessary to contain the string and
     returns a pointer to the string.  The caller should free any releasable
     memory, when the new string is no longer required, by calling acl_free()
     with the (void*)char returned by acl_to_any_text() as an argument.

     On success, this function returns a pointer to the text representation of
     the ACL.  On error, a value of (char *)NULL is returned, and errno is set

     If any of the following conditions occur, the acl_to_any_text() function
     returns a value of (char *)NULL and sets errno to the corresponding

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

			The ACL referenced by acl contains one or more improp‐
			erly formed ACL entries, or for some other reason can‐
			not be translated into the text form of an ACL.

     [ENOMEM]		The character string to be returned requires more mem‐
			ory than is allowed by the hardware or system-imposed
			memory management constraints.

     This is a non-portable, Linux specific extension to the ACL manipulation
     functions defined in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).
