NAME

       explain_acl_to_text_or_die - convert an ACL to text and report errors

SYNOPSIS

       #include <libexplain/acl_to_text.h>
       char *explain_acl_to_text_or_die(acl_t acl, ssize_t *len_p);
       char *explain_acl_to_text_on_error(acl_t acl, ssize_t *len_p);

DESCRIPTION

       The explain_acl_to_text_or_die function is used to call the acl_to_text(3) system call. On
       failure an explanation will be printed to stderr, obtained from the explain_acl_to_text(3)
       function, and then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_acl_to_text_on_error function is used to call the acl_to_text(3) system call.
       On  failure  an   explanation   will   be   printed   to   stderr,   obtained   from   the
       explain_acl_to_text(3) function, but still returns to the caller.

       acl     The acl, exactly as to be passed to the acl_to_text(3) system call.

       len_p   The len_p, exactly as to be passed to the acl_to_text(3) system call.

RETURN VALUE

       The  explain_acl_to_text_or_die  function  only returns on success, see acl_to_text(3) for
       more information. On failure, prints an explanation and exits, it does not return.

       The explain_acl_to_text_on_error function always returns the value return by  the  wrapped
       acl_to_text(3) system call.

EXAMPLE

       The explain_acl_to_text_or_die function is intended to be used in a fashion similar to the
       following example:
              char *result = explain_acl_to_text_or_die(acl, len_p);
