NAME¶
explain_utimes_or_die - change file access and modify times and report errors
SYNOPSIS¶
#include <libexplain/utimes.h>
void explain_utimes_or_die(const char *pathname, const struct timeval *data);
int explain_utimes_on_error(const char *pathname, const struct timeval *data);
DESCRIPTION¶
The
explain_utimes_or_die function is used to call the
utimes(2)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_utimes(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The
explain_utimes_on_error function is used to call the
utimes(2)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_utimes(3) function, but still returns to the
caller.
- pathname
- The pathname, exactly as to be passed to the
utimes(2) system call.
- data
- The data, exactly as to be passed to the utimes(2)
system call.
RETURN VALUE¶
The
explain_utimes_or_die function only returns on success, see
utimes(2) for more information. On failure, prints an explanation and
exits, it does not return.
The
explain_utimes_on_error function always returns the value return by
the wrapped
utimes(2) system call.
EXAMPLE¶
The
explain_utimes_or_die function is intended to be used in a fashion
similar to the following example:
explain_utimes_or_die(pathname, data);
