The function is only explicitly defined for -values between -90 and +90 for -.I latitude -and values between -180 and +180 for and -.IR longitude . -Other values may or may not work, no error is thrown if used. -.SH "RETURN VALUE" -Upon successful completion, the function sets -.B errno -to 0 and returns the Sun's current apparent elevation, measured in -degrees above the horizon. On failure, the function returns an -arbitrary value (happens to always be 0.0) and sets -.B errno -an a non-zero value. -.SH ERRORS -The function may fail for any reason specified for -.BR clock_gettime (3), -and set the value of -.B errno -to the same values. -.B errno -is always set to 0 on success. -.SH "FUTURE DIRECTIONS" -None. -.SH "SEE ALSO" -.BR libred.h (0), -.BR libred (7), -.BR libred_check_timetravel (3), -.BR libred_init_colour (3) |
