Section1: Section 1: The Ephemeris file related functions
Description
Several initialization functions
Usage
swe_set_ephe_path(path)
swe_close()
swe_set_jpl_file(fname)
swe_version()
Arguments
path
Directory for the sefstars.txt, swe_deltat.txt and jpl files
fname
JPL ephemeris name as string (JPL ephemeris file, e.g. de431.eph)
Value
swe_version returns Swiss Ephemeris software version as string
Details
swe_set_ephe_path()
This is the first function that should be called
before any other function of the Swiss Ephemeris. Even if you don't
want to set an ephemeris path and use the Moshier ephemeris, it is
nevertheless recommended to call swe_set_ephe_path(NULL), because this
function makes important initializations. If you don't do that, the
Swiss Ephemeris may work, but the results may be not 100% consistent.
swe_close()
At the end of your computations this function releases most
resources (open files and allocated memory) used by Swiss Ephemeris.
swe_set_jpl_file()
Set name of JPL ephemeris file.
swe_version()
The function provides the version number of the Swiss Ephemeris software.
