ACL_STRIP_NP(3) 					   BSD Library Functions Manual 					   ACL_STRIP_NP(3)

NAME

     acl_strip_np -- strip extended entries from an ACL

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

     acl_t
     acl_strip_np(const acl_t acl, int recalculate_mask);

DESCRIPTION

     The acl_strip_np() function returns a pointer to a trivial ACL computed from the ACL pointed to by the argument acl.

     This function may cause memory to be allocated.  The caller should free any releasable memory, when the new ACL is no longer required, by
     calling acl_free(3) with the (void*)acl_t as an argument.

     Any existing ACL pointers that refer to the ACL referred to by acl shall continue to refer to the ACL.

RETURN VALUES

     Upon successful completion, this function shall return a pointer to the newly allocated ACL.  Otherwise, a value of (acl_t)NULL shall be
     returned, and errno shall be set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_init() function shall return a value of (acl_t)NULL and set errno to the corresponding
     value:

     [EINVAL]		Argument acl does not point to a valid ACL.

     [ENOMEM]		The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

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.

HISTORY

     POSIX.1e support was introduced in FreeBSD 4.0.  The acl_strip_np() function was added in FreeBSD 8.0.

ACL_TO_TEXT(3)						   BSD Library Functions Manual 					    ACL_TO_TEXT(3)

NAME

     acl_to_text -- convert an ACL to text

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

     char *
     acl_to_text(acl_t acl, ssize_t *len_p);

DESCRIPTION

     The acl_to_text() function translates the ACL pointed to by argument acl into a NULL terminated character string.	If the pointer 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 len_p.
     The format of the text string returned by acl_to_text() for an ACL of type ACL_TYPE_EXTENDED differs from that specified by the POSIX.1e
     standard, and this function cannot translate between formats.

     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(3) with the (void*)char as an argument.

RETURN VALUES

     Upon successful completion, the function shall return a pointer to the long text form of an ACL.  Otherwise, a value of (char*)NULL shall be
     returned and errno shall be set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_to_text() function shall return a value of (acl_t)NULL and set errno to the corresponding
     value:

     [EINVAL]		Argument acl does not point to a valid ACL.

			The ACL denoted by acl contains one or more improperly formed ACL entries, or for some other reason cannot be translated
			into a text form of an ACL.

     [ENOMEM]		The character string to be returned requires more memory than is allowed by the hardware or software-imposed memory man-
			agement constraints.
