-.Dt ACL_TO_TEXT 3
-.Os FreeBSD 4.0
-.Sh NAME
-.Nm acl_to_text
-.Nd Convert an ACL to Text
-.Sh SYNOPSIS
-.Fd #include <sys/types.h>
-.Fd #include <sys/acl.h>
-.Ft char *
-.Fn acl_to_text "acl_t acl" "ssize_t *len_p"
-.Sh DESCRIPTION
-The
-.Fn acl_to_text
-function translates the ACL pointed to by argument
-.Va acl
-into a NULL terminated character string. If the pointer
-.Va len_p
-is not NULL, then the function shall return the length of the string (not
-including the NULL terminator) in the location pointed to by
-.Va len_p .
-The format of the text string returned by
-.Fn acl_to_text
-shall be the POSIX.1e long ACL form.
-
-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
-.Xr acl_free 3
-with the
-.Va (void*)char
-as an argument.
-.Sh IMPLEMENTATION NOTES
-FreeBSD's support for POSIX.1e interfaces and features is still under
-development at this time.
-.Sh RETURN VALUES
-Upon successful completion, the function shall return a pointer to the
-long text form of an ACL. Otherwise, a value of
-.Va (char*)NULL
-shall be returned and
-.Va errno
-shall be set to indicate the error.
-.Sh ERRORS
-If any of the following conditions occur, the
-.Fn acl_to_text
-function shall return a value of
-.Va (acl_t)NULL
-and set
-.Va errno
-to the corresponding value:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-Argument
-.Va acl
-does not point to a valid ACL.
-
-The ACL denoted by
-.Va acl
-contains one or more improperly formed ACL entries, or for some other
-reason cannot be translated into a text form of an ACL.
-.It Bq Er ENOMEM
-The character string to be returned requires more memory than is allowed
-by the hardware or software-imposed memory management constraints.
-.El
-.Sh SEE ALSO
-.Xr acl 3 ,
-.Xr acl_free 3 ,
-.Xr acl_from_text 3 ,
-.Xr posix1e 3
-.Sh STANDARDS
-POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
-of the draft continues on the cross-platform POSIX.1e implementation
-mailing list. To join this list, see the FreeBSD POSIX.1e implementation
-page for more information.
-.Sh HISTORY
-POSIX.1e support was introduced in
-.Fx 4.0 ,
-and development continues.
-.Sh AUTHORS
-.An Robert N M Watson
-.Sh BUGS
-These features are not yet fully implemented. In particular, the shipped
-version of UFS/FFS does not support storage of additional security labels,
-and so is unable to (easily) provide support for most of these features.
-
-.Fn acl_from_text
-and
-.Fn acl_to_text
-rely on the
-.Xr getpwent 3
-library calls to manage username and uid mapping, as well as the
-.Xr getgrent 3
-library calls to manage groupname and gid mapping. These calls are not
-thread safe, and so transitively, neither are
-.Fn acl_from_text
-and
-.Fn acl_to_text .
-These functions may also interfere with stateful
-calls associated with the
-.Fn getpwent
-and
-.Fn getgrent
-calls.
