Function Documentation

char* explain_acl_to_text_on_error	(	acl_t	acl,
		ssize_t *	len_p
	)

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.

Parameters:

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.

Returns:

The value returned by the wrapped acl_to_text(3) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 char *result = explain_acl_to_text_on_error(acl, len_p);
 if (!result)
 {
     ...cope with error
     ...no need to print error message
 }

char* explain_acl_to_text_or_die	(	acl_t	acl,
		ssize_t *	len_p
	)

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).

Parameters:

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.

Returns:

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

Example:

This 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);
