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 charac-ter character
ter 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. Oth-erwise, Otherwise,
erwise, 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 management constraints.
