get_healpix_main_dir, 
A few functions are available to return the full path to HEALPix main directory
and its data and test subdirectories. This allow those paths to be
controlled by preprocessing macros or environment variables in case of
non-standard installation of the HEALPix directory structure.
Location in HEALPix directory tree:
src/f90/mod/paramfile_io.F90
FUNCTIONS:
hmd = get_healpix_main_dir()
| | |
| returns the full path to the main
HEALPix directory. It will be determined, in this
order, from the value of the
preprocessing macros HEALPIX and HEALPIXDIR
if they are defined or the
environment variable $HEALPIX otherwise |
|
hdd = get_healpix_data_dir()
| | |
| returns the full path to
HEALPix data subdirectory. It will be determined
from the preprocessing macro HEALPIXDATA or the environment variable $HEALPIXDATA. If both fail, it will return the list of directories {. ../data ./data .. $HEALPIX $HEALPIX/data $HEALPIX/../data
$HEALPIX data} separated by LineFeed. |
|
htd = get_healpix_test_dir()
| | |
| returns the full path to
HEALPix test subdirectory. It will be determined,
in this order, from the preprocessing macro HEALPIXTEST, the environment
variable $HEALPIXTEST or $HEALPIX/test. |
