NAME

explain_lutimes_or_die - modify file timestamps and report errors

SYNOPSIS

#include <libexplain/lutimes.h>

void explain_lutimes_or_die(const char *pathname, const struct timeval *data);
int explain_lutimes_on_error(const char *pathname, const struct timeval *data);

DESCRIPTION

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

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

pathname: The pathname, exactly as to be passed to the lutimes(3) system call.
data: The data, exactly as to be passed to the lutimes(3) system call.

RETURN VALUE

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

The explain_lutimes_on_error function always returns the value return by the wrapped lutimes(3) system call.

EXAMPLE
