NAME¶

explain_utimensat_or_die - change file timestamps and report errors

SYNOPSIS¶

#include <libexplain/utimensat.h>

void explain_utimensat_or_die(int fildes, const char *pathname, const struct timespec *data, int flags);
int explain_utimensat_on_error(int fildes, const char *pathname, const struct timespec *data, int flags);

DESCRIPTION¶

The explain_utimensat_or_die function is used to call the utimensat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_utimensat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_utimensat_on_error function is used to call the utimensat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_utimensat(3) function, but still returns to the caller.

fildes

The fildes, exactly as to be passed to the utimensat(2) system call.

pathname

The pathname, exactly as to be passed to the utimensat(2) system call.

data

The data, exactly as to be passed to the utimensat(2) system call.

flags

The flags, exactly as to be passed to the utimensat(2) system call.

RETURN VALUE¶

The explain_utimensat_or_die function only returns on success, see utimensat(2) for more information. On failure, prints an explanation and exits, it does not return.

The explain_utimensat_on_error function always returns the value return by the wrapped utimensat(2) system call.

EXAMPLE¶

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

explain_utimensat_or_die(fildes, pathname, data, flags);

SEE ALSO¶

utimensat(2)

explain_utimensat(3)

exit(2)
