SYNOPSIS

#include <libexplain/acl_from_text.h>

acl_t explain_acl_from_text_or_die(const char *text);
acl_t explain_acl_from_text_on_error(const char *text);

DESCRIPTION

The B]explain_acl_from_text_or_die function is used to call the I]acl_from_text(3) system call. On failure an explanation will be printed to I]stderr, obtained from the I]explain_acl_from_text(3) function, and then the process terminates by calling CW]exit(EXIT_FAILURE).

The B]explain_acl_from_text_on_error function is used to call the I]acl_from_text(3) system call. On failure an explanation will be printed to I]stderr, obtained from the I]explain_acl_from_text(3) function, but still returns to the caller.
I]text The text, exactly as to be passed to the I]acl_from_text(3) system call.

RETURN VALUE

The B]explain_acl_from_text_or_die function only returns on success, see I]acl_from_text(3) for more information. On failure, prints an explanation and exits, it does not return.

The B]explain_acl_from_text_on_error function always returns the value return by the wrapped I]acl_from_text(3) system call.

EXAMPLE

The B]explain_acl_from_text_or_die function is intended to be used in a fashion similar to the following example:
acl_t result = explain_acl_from_text_or_die(text);
