Calculate the time of next rise, set and transit for an object a body, usually Sun, a planet or Moon. E.g. it's sure, that rise, set and transit will be in range.
Definition: rise_set.c:425

Calculate the time of next rise, set and transit for an object a body, usually Sun, a planet or Moon. E.g. it's sure, that rise, set and transit will be in range.
Definition: rise_set.c:455
ln_equ_posn
Equatorial Coordinates.

ln_get_object_next_rst
int LIBNOVA_EXPORT ln_get_object_next_rst(double JD, struct ln_lnlat_posn *observer, struct ln_equ_posn *object, struct ln_rst_time *rst)
Calculate the time of next rise, set and transit for an object not orbiting the Sun. E.g. it's sure, that rise, set and transit will be in range. This function is not too precise, it's good to get general idea when object will rise.
Definition: rise_set.c:190

int LIBNOVA_EXPORT ln_get_object_next_rst_horizon(double JD, struct ln_lnlat_posn *observer, struct ln_equ_posn *object, double horizon, struct ln_rst_time *rst)
Calculate the time of next rise, set and transit for an object not orbiting the Sun. E.g. it's sure, that rise, set and transit will be in range.
Definition: rise_set.c:228
ln_lnlat_posn
Ecliptical (or celestial) Longitude and Latitude.
Definition: ln_types.h:200
ln_rst_time
Rise, Set and Transit times.
Definition: ln_types.h:317

ln_get_object_rst
int LIBNOVA_EXPORT ln_get_object_rst(double JD, struct ln_lnlat_posn *observer, struct ln_equ_posn *object, struct ln_rst_time *rst)
