explain_acl_set_file_or_die(3) set an ACL by filename and report errors

SYNOPSIS

#include <libexplain/acl_set_file.h>

void explain_acl_set_file_or_die(const char *pathname, acl_type_t type, acl_t acl);
int explain_acl_set_file_on_error(const char *pathname, acl_type_t type, acl_t acl);

DESCRIPTION

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

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

pathname
The pathname, exactly as to be passed to the acl_set_file(3) system call.
type
The type, exactly as to be passed to the acl_set_file(3) system call.
acl
The acl, exactly as to be passed to the acl_set_file(3) system call.

RETURN VALUE

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

The explain_acl_set_file_on_error function always returns the value return by the wrapped acl_set_file(3) system call.

EXAMPLE

The explain_acl_set_file_or_die function is intended to be used in a fashion similar to the following example:
explain_acl_set_file_or_die(pathname, type, acl);
