/****************************************************************************
+ * Name: futimes
+ *
+ * Description:
+ * futimens() update the timestamps of a file with nanosecond precision.
+ * This contrasts with the historical utime(2) and utimes(2), which permit
+ * only second and microsecond precision, respectively, when setting file
+ * timestamps. With futimens() the file whose timestamps are to be updated
+ * is specified via an open file descriptor, fd.
+ *
+ * Input Parameters:
+ * fd - Specifies the fd to be modified
+ * times - Specifies the time value to set
+ *
+ * Returned Value:
+ * On success, futimens() return 0.
+ * On error, -1 is returned and errno is set to indicate the error.
