The following example shows how to stop the execution on the error.
t_calcephbin * eph;
/* set the error handler to stop on error */
calceph_seterrorhandler(2, 0);
/* open the ephemeris file */
eph = calceph_open("example1.dat");
/*... computation ... */
The following example shows how to define a custom error handler function.
/*-----------------------------------------------------------------*/
/* custom error handler */
/*-----------------------------------------------------------------*/
static void myhandler(const char *msg)
{
puts("The calceph calls the function myhandler");
printf("The message contains %d characters\n", (int)strlen(msg));
puts("The error message is :");
puts("----------------------");
puts(msg);
puts("----------------------");
puts("The error handler returns");
}
int main(void)
{
t_calcephbin * eph;
/* set the error handler to stop on error */
calceph_seterrorhandler(3, myhandler);
/* open the ephemeris file */
eph = calceph_open("example1.dat");
/*... computation ... */
return 0;
}
