ACLTOTEXT(3) BSD Library Functions Manual ACLTOTEXT(3)

NAME
     aaccllttootteexxtt - convert an ACL to text

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>
     ##iinncclluuddee <>

     char *
     aaccllttootteexxtt(aclt acl, ssizet *lenp);

DESCRIPTION
     The aaccllttootteexxtt() function translates the ACL pointed to by argument acl
     into a NULL terminated character string.  If the pointer lenp is not
     NULL, then the function shall return the length of the string (not
     including the NULL terminator) in the location pointed to by lenp.  The
     format of the text string returned by aaccllttootteexxtt() for an ACL of type
     ACLTYPEEXTENDED 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 aclfree(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.

EERRRROORRSS
     If any of the following conditions occur, the aaccllttootteexxtt() function
     shall return a value of (aclt)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 mem-
                        ory than is allowed by the hardware or software-
                        imposed memory management constraints.
