explain_lutimes_or_die - modify file timestamps and report errors

#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);

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.

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

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.

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

explain_lutimes_or_die(pathname, data);

lutimes(3)
modify file timestamps
explain_lutimes(3)
explain lutimes(3) errors
exit(2)
terminate the calling process
