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

     acl_to_text -- convert an ACL to text

     Standard C Library (libc, -lc)

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

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

     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.

     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.

     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.

     acl(3), acl_free(3), acl_from_text(3), posix1e(3)

     POSIX.1e is described in IEEE POSIX.1e draft 17.
