heights.c

A detailed example on how to retreive and handle the 10 last water heights of a station (Morlaix [Lannidy] in this example).

#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <vigicrues.h>

    puts("Last 10 water heights for station \"Morlaix [Lannidy]\":");
    init = 1;
  }
  
  struct tm *p_date = localtime(&(p_data->timestamp));
  
  printf("%.2fm published on %s", p_data->value, asctime(p_date));
  
  return VIGICRUES_SUCCESS;
}

int main(void)

                                            "J260301501", VIGICRUES_HEIGHT, 10,

                                            NULL);
  
  return (status == VIGICRUES_SUCCESS) ? EXIT_SUCCESS : EXIT_FAILURE;
